Hadoop Interview Questions Part-3

1) What are the most common input formats in Hadoop?

There are three most favored feedback types in Hadoop:

Text Reviews Format: Conventional feedback framework in Hadoop.

Key Value Reviews Format: used for basically published written text information where the information are broken into lines

Sequence Computer data file Reviews Format: used for learning information in sequence

2) Figure out DataNode and how does NameNode cope with DataNode failures?

DataNode stores details in HDFS; it is a node where actual details prevails in the data file system. Each datanode provides a beat amount idea to tell that it is in lifestyle. If the namenode does not get a idea from datanode for 15 minutes, it opinions it to be dead or out of place, and starts replication of stops that were organized on that details node such that they are organized on some more details node.A BlockReport contains record of all stops on a DataNode. Now, this method starts to copy what were held in dead DataNode.

The NameNode manages the replication of information blocksfrom one DataNode to other. In the process, the replication details transactions directly between DataNode such that the details never goes the NameNode.

3) What are the primary methods of a Reducer?

The three primary methods of a Reducer are:

setup(): this method is used for developing various aspects like feedback details sizing, assigned storage space storage cache.

public gap set up (context)

reduce(): core of the Reducer always known as once per key with the associated reduced task

public gap reduce(Key, Value, context)

cleanup(): this method is known as to fresh short-term information, only once at the end of the task

public gap clean-up (context)

4) What is SequenceFile in Hadoop?

Extensively used in MapReduce I/O types, SequenceFile is a set data file containing binary key/value places. The map answers are stored as SequenceFile inner. It provides Viewers, Writer and Sorter classes. The three SequenceFile types are:

Uncompressed key/value details.

Record compressed key/value details – only ‘values’ are compressed here.

Block compressed key/value details – both key elements and concepts are collected in ‘blocks’ individually and compressed. The size of the ‘block’ is configurable.

5) What is Job Monitoring system aspect in Hadoop?

Job Tracker’s primary function is resource management (managing the perform trackers), tracking resource availability and process life-cycle management (tracking the taks enhancement and error tolerance).

It is a there are runs using another node, not on a DataNode often.

Job Monitoring system provides with the NameNode to identify details place.

Finds the best Process Monitoring system Nodes to function tasks on given nodes.

Monitors individual Process Trackers and sends the overall job returning again to the client.

It routes the efficiency of MapReduce workloads local to the slave node.

6) What is the use of RecordReader in Hadoop?

Since Hadoop separates details into various stops, RecordReader is used to analyze the slit details into individual record. For example, if our feedback details are separated like:

Row1: Welcome to

Row2: Intellipaat

It will be research as “Welcome to Intellipaat” using RecordReader.

7) What is Risky Performance in Hadoop?

One restriction of Hadoop is that by circulating the duties on several nodes, there are possibilities that few slowly nodes restrict the relax of the system. There are various factors for the duties to be slowly, which are sometimes quite difficult to identify. Instead of determining and solving the slow-running projects, Hadoop tries to identify when the work operates more slowly than predicted and then releases other comparative process as back-up. This back-up procedure in Hadoop is Risky Performance.

Oracle Certification now teaches you DBMS architecture

What does Two-Tier Framework mean?

A two-tier architecture is an application package architecture in which a presentation layer or interface operates on a customer, and a data layer or data structure gets saved on a server. Breaking these two elements into different places symbolizes a two-tier architecture, as instead of a single-tier architecture. Other kinds of multi-tier architectures add extra levels in allocated application style.

You can join the oracle dba course to know more about this field.

Two-Tier Architecture

Experts often compare a two-tier architecture to a three-tier architecture, where a third program or business part is included that serves as a middleman between the client or presentation layer and the data layer.

This can improve the efficiency of it and help with scalability. It can also remove many types of problems with misunderstandings, which can be triggered by multi-user accessibility in two-tier architectures.

However, the innovative complexness of three-tier architecture may mean more cost as well as.

WHAT IS NEW WITH DATABASE LIFECYCLE MANAGEMENT?

WHAT IS NEW WITH DATABASE LIFECYCLE MANAGEMENT?

Companies have instructed a lot of attention recently to consolidation, automated, and reasoning projects in their information control surroundings. This will supposedly lead to reduced demand for information supervisors and the need for fewer DBAs per groups of data source. However, the opposite seems to be happening. In fact, there is an increasing need for more talent, as well as expertise to manage through increasing complexness. A new study among information professionals, supervisors, and professionals discovers that a more challenging information environment is coming up due to a confluence of factors.

The analysis, performed by Unisphere Research, a department of Information Today, Inc., and subsidized by Idera, included the reactions of more than 300 DBTA readers who signify a variety of sectors and company dimensions.

Half of the information shops covered in laptop computer have started in proportions over the course of the last 5 years—some considerably. Near to one in four participants reports development exceeding 25% of their organization’s original employees dimension. By contrast, only 10% of participants say their employees have reduced in proportions.

What’s driving the continuing development in data source staffing? For the most part, companies have been expanding—adding more lines, more services, and increasing deal amounts. Sixty-one percent of websites experiencing employees development say the increasing volume of company demands including more information supervisors to their groups. The development of information itself—exacerbated by big data—is also a adding factor, mentioned by 50 % of this group. The rise of new information frameworks, such as Hadoop or information factory expansions, is yet another driver among 44% of websites.

In addition, the vast majority, 89%, agree that the complexness of their data source surroundings has increased over the past 5 years. Near to 50 percent, 46%, state that their data source surroundings have started “significantly” or “extremely” more complex during now. As with areas that caused the ongoing development in data source employees dimensions, both company development information development are also including complexness to information surroundings.

The turn to reasoning processing, at least for mission-critical zazzle corporation, will be a slow one. Only 19% of information supervisors indicate that they plan to go a good section of their zazzle corporation (defined as more than 25% of their total information stores) to a public reasoning, while 26% plan to go a good section of their information to private or multiple reasoning arrangements.

Are any practical measures being taken to deal with this complexity? Virtualization and automated are the top options being implemented by information supervisors to provide some much-needed convenience to increasingly heterogeneous surroundings. The use of control and settings resources is seen as a way forward for 38% of participants. About one-third of participants review they are implementing data source lifecycle control (DLM) strategies to deal with increasing complexness within their information surroundings. (DLM involves synchronized processes, resources, and people to improve all aspects of the lifecycle of information, including information structure and modelling, data source design, tracking, administration, security, storage, and preserving.)

Data supervisors review a variety of concrete company advantages that their organizations are gaining due to their DLM projects. More up-time of computer is the leading benefit being realized. A number, 57%, say they have experienced reduced system time to recover as due to of their DLM events. Another 55% of participants claim that their projects have made information more available to their end users. Confidence in the information itself is also up at 38% of websites.

Yet, information supervisors have also experienced difficulties in their projects to apply DLM. Half, for example, claim that their projects have been stymied by the need for greater funding or employees a chance to engage in DLM. At least one-third of participants to laptop computer also indicate that their DLM programs do not have as high a priority at other identical projects, such as application lifecycle control. The same percentage of participants see other barriers, such as a lack of exposure to the issues that may be impacting data source performance. There are many oracle institutes in Pune and oracle dba course in Pune to make your career in this field.

hadoop interview questions part 2

[snehasingh9012-blog]

There are many queries which ranges from date manipulation, receiving server info, get execution status, calculate database size etc.

Get the first day of the month

Quickly returns the first day of current month. Instead of present month you want to discover first day of the month in the case of date, substitute SYSDATE with any date column/value.

SELECT TRUNC (SYSDATE, ‘MONTH’) “First day of present month”

FROM DUAL;

Acquire the last day of the month

This query is related to above but returns last day of the present month. The only thing which it takes care of is the leap year.

So if there are 29 days in Feb, it will return 29/2. Also identical to above query replace SYSDATE with any other time frame column/value to discover last day of that particular month.
