Setting up Dev Endpoint using Apache Zeppelin with AWS Glue

AWS Glue is a powerful tool that is managed, relieving you of the hassle associated with maintaining the infrastructure. It is hosted by AWS and offers Glue as Serverless ETL, which converts the code into Python/Scala and execute it in Spark environment.

AWS Glue provisions all the required resources (Spark cluster) at runtime to execute the Spark Job which it takes ~7-10 mins and then starts executing your actual ETL code. To reduce this time AWS Glues provides Development endpoint, which can be configured in Apache Zeppelin (provisioned with the spark environment) to interactively, run, debug and test ETL code before deploying as Glue job or scheduling the ETL process.

In order to successfully set up the Dev Endpoint on AWS Glue, first let us understand some of its prerequisites:

An IAM Role for the Glue Dev Endpoint with the necessary policies. E.g.: AWSGlueServiceRole

Table in Glue Data Catalog and the necessary connection

I am assuming that you know your way around VPC networking, security groups, etc., E.g.: The Dev Endpoint requires a security group that allows the port 22, since we need that for the SSH tunneling.

Further, we can move on to the process involved in setting up the Dev Endpoint on AWS Glue. Here’s how it goes:

Create an SSL Key Pair

You can create it using PuTTyGen tool or you can create it under AWS EC2 -> Network & Security -> Key Pairs

You need the Public Key which should look like:

You will need the Private Key in .ppk format. If you’re using PuTTYgen, you will get it in the .ppk format whereas in case of EC2 you will get the file in .pem format and you will have to convert it into .ppk using the PuTTygen conversion tool.

Make sure that the file has permissions of 400 or 600 – in case of Linux whereas in case of windows follow the below steps:

Right click on PEM file > Properties > Security > Advanced.

Make sure that you are the owner of the file and have disabled the inheritance (once you have disabled it, it will look like below screenshot)

Spin up the AWS Glue Dev Endpoints:

Create it by going to AWS Glue -> Dev endpoints -> Add endpoint and you should see this:

In Development endpoint name: Give it any name; IAM Role: Select the role which you’ve created; and Click Next.

Choose “Skip Networking Information” if you have S3 data stores, otherwise you can select the rest two as per your instances or security groups. Click Next.

Now from your key pair values, paste the Public Key here as shown below and click Next:

Review the details and click on Finish:

Now let the process run and wait until the Provisioning status shows a “READY” State.

SSH tunnel for Glue Dev Endpoint: When your dev endpoint is provisioned, check that its network interface has a public address attached to it and make note of it (e.g., ec2-xx-xxx-xxx-xx.us-west-2.compute.amazonaws.com).

a. Create SSH tunnel using PuTTY:

b. Using SSH:

Zeppelin Notebook:

Write your first Glue program:

Download the Zeppelin Notebook 0.7.3 version.

Unzip the file and copy the folder under C: Drive.

Go to localhost:8080

On the top-right corner, click anonymous > interpreter > Search for spark > edit

Have Connect to existing process checked

Set host to localhost and port to 9007

Under properties, set master to yarn-client

Remove executor.memory and spark.driver.memory properties if they exist.

Save, Ok.

Under Notebook, create Notebook > select Spark Interpreter

Try your program and execute it.

And with that, your AWS Glue is up and running. Obviously this was just scratching the surface. There is a lot more to learn but I’ll cover those in another blog.

Reach out to us at Nitor Infotech to learn more about how you can deploy AWS Glue to simplify your ETL work, and if you’re in the mood for some light reading, you can take a look at a blog that I had penned down about AWS Redshift PartiQL.

Various Command Line Options of PuTTY in Linux

Below are few important command line options in the Linux operating system for PuTTY:

PuTTYgen [-t keytype [-b bits] [-q] | keyfile] [-C new-comment] [-P] [-O output-type | -p | -l | -L] [-o output-file]

Options:

Keyfile – It is the name of the existing key file to read at the time of changing the current key.

–t keytype – The command specifies the type of key to creating. Its acceptable values are RSA and dsa.rsa1.

-b bits – This command specifies a total number of bit in a particular key. 1024 is the perfect size for DSA key, while 2048 or 4096 are the perfect size for RSA keys.

–q – The command suppresses the message about progress at the time of key generation.

-C new-comment – The command will specify the comment to describe the key. It can be used for the new and/or existing key. Key operation is not affected by a comment. However, it is used to recognize the key owner, it’s not reliable completely as any value can be applied to it.

–P – Using the command will update the passphrase of a key. Passphrase helps to encrypt the private key. As passphrase can’t add or update on a command line, it prompts a new passphrase tool to alter it.

–old-passphrase-file – The old password of the key remains in this file. The command is used when the key is protected by a passphrase.

–new-passphrase file – This command prompts the new passphrase of the key. It comes in the action either at the time of generating a new key or while applying –P command to change the passphrase.

-O output-type – This command defines what to give in output. By default, the private key is the output.

Thus, above are the prominent commands of PuTTYgen in Linux operating system. Besides that, there are many other commands available to perform various tasks from the command prompt in Linux at flank speed.

The above description is a detailed brief on downloading and running PuTTYgen on all major operating systems. For further details please check the Download PuTTY page.

Background

Most Unix-like systems are configured to use the SSH protocol for remote access, but most SSH client applications do not support PIV as required by Federal policy. Putty-CAC, a fork of the Open Source Putty SSH client, resolves this issue.

Note that Van Dyke Secure CRT, a commercial product, also supports PIV SSH login for multiple platforms, including Windows and Mac.

Installing PuTTY-CAC

If you have a forge.mil account, download the latest Putty-CAC package from forge.mil. If you do not have access to forge.mil, you can also download it at https://risacher.org/putty-cac. Source code is available at https://github.com/risacher/putty-cac

There is no installer available for the binaries, so you must either: ● Place the executable files in a directory that you have execute rights over. ● Build an installation package to install the executables in the location you choose. This will enable the Putty-CAC applications to be available from the Start Menu.

At a minimum, you must install the following packages: ● putty.exe ● pageant.exe

Verify the version of PuTTY that was installed by opening the application and clicking About in the lower left corner.

Launch pageant from the PuTTY install directory, (eg, C:Program FilesPutty-CAC). Pageant will appear in the taskbar on the bottom right of your desktop;it will not open a window.

You must now insert the CAPI Key and configure PuTTY-CAC. Follow the steps below.

Putty Alternative Mac

Add CAPI Key into Pageant

Open Windows Explorer or click Start > Computer.

Open Pageant by clicking the executable.

A window will not open, but the Pageant icon will appear on the menu bar. Right-click the icon and select View Keys.

The Pageant Key List window will appear. Click Add CAPI Cert.

Select your Smart Card Logon certificate from the Windows Security window.

● Make sure you choose the correct certificate! Select “Click here to view certificate properties,” click “Details,” scroll half-way, and locate Enhanced Key Usage. It should begin with “Smart Card Logon;” this indicates it is the correct certificate. If you do not see this field, select a different certificate. Note: If multiple certificates exist, you may want to clear out the expired or revoked certificates by following How To – FIXME: PIV Card – Clear certificate store. ● Click OK to close the details window.

Highlight the correct Smart Card certificate and click OK.

The Pageant Window will now display the certificate information.

Click Close.

Warning: You must re-add your certificate every time pageant is started.

Configure PuTTY-CAC

Right-click the Pageant icon again from the menu bar and select New Session. This will launch PuTTY.

From within PuTTY, enter the destination IP address or hostname in the Host Name (or IP address) textbox to setup a new profile, or if you already have profiles set up in PuTTY, load that profile.

Note: If you have multiple destination profiles, you will have to do the following steps for each profile

Enter a descriptive name under Saved Sessions textbox (if setting up a new profile).

On left panel, select Connection > SSH > CAPI thencheck the box beside the words Attempt “CAPI Certificate” (Key-only) auth (SSH-2).

From within PuTTY, select Connection > SSH > Auth then select both “Allow agent forwarding” and “Allow attempted changes of username in SSH-2.”

Click Session, then Save. This profile is now configured for PIV logon.

To get your PIV card’s SSH key, in PuTTY, go to Connection > SSH > CAPI and select the browse button on the right side. This will automatically fill in the “Cert” and “SSH keystring” fields.

Copy and paste the SSH keystring value from PuTTY into Notepad as you will need to include the SSH key when you contact the jumpbox support team or create a service ticket.

The configuration file should contain “Host *” and “ForwardAgent yes” and exist in the same folder where they place the SSH key.

In Saved Sessions, click Save to save your configuration.

Putty Free Download

Verify PIV Login

Ssh And Putty Download For Mac

Open Pageant (if not already running) and make sure your CAPI key is populated, close the Pageant window. Right click the Pageant icon and choose “New Session”. This will open PuTTY-CAC.

Load one of your saved sessions that you previously configured for PIV logon.

When prompted, enter your remote Unix/Linux account name, and you should be prompted for your PIV PIN.

Enter your PIN, click OK and you should be logged in.

Once logged in, run ‘ssh-add –l’ to ensure that the forwarding agent is working. If you do not see the key printed when you run this command, something is wrong and you will not be prompted for your PIN if you ssh further into the environment.

Both the cert key that was pasted into the .ssh/authorized_keys and the config file need to be copied or scp’d to all the servers you will connect to in the data center. If the forwarding agent is working when you ssh to a server beyond the jumphost, you should be prompted for the PIN again.

After each server you ‘jump’ to, the output of ssh-add –l should always show the key. If not, either permissions are wrong or a file is mislabeled, or missing.

Convert private key generated via OCI Console to ppk

I am pretty new on the Oracle Cloud Infrastructure technology, so maybe I am talking about something you already know. But anyway I prefer to share this case: it can help if you encounter the same problem as me. Let’s take the risk to have too much information rather than nothing! The problem I was doing some tests on the new MySQL Database Service and during the setup I decided to generate my ssh keys via the OCI console: When I tried to connect via PuTTY or MobaXterm to my compute instance using the opc account and my private key (generated previously), I got the following error: Looking at the keys generated via the Oracle Cloud console, I saw that they were defined in the following format: The solution Actually I don’t work directly on a Linux system. So I need to convert my private key if I want to make it usable via my connection tools. First step is to transform it to RSA format. I can do it using OpenSSL: # openssl rsa -in ssh-key-2020-11-24.key -out ssh-key-2020-11-24.rsa Second and last step is to convert it to ppk format. I can do it using PuTTYgen. I load the private key: I filter on all files types: I select my RSA key and I click on Open: I click on Ok on the following message: and then on Save private key: So I save the key with a ppk format: Tests I can now use my private key to connect to my OCI compute instance via PuTTY: or MobaXterm: Hope this can help you!
