Hadoop GitHub

The Apache Hadoop project is hosted on GitHub, and you can find its repository at github.com/apache/hadoop. This repository contains the source code for Hadoop and its various components, such as Hadoop Common, HDFS, and MapReduce. It’s a comprehensive repository featuring over 14,000 stars and 8,800 forks, indicating its popularity and widespread use in the open-source community.

Additionally, the process involves several steps if you’re interested in building Hadoop from the source. Firstly, you would clone the repository and then build the distribution package. This process is done using Maven, and you might need to run unit tests as part of the build process. As a large and complex project, Hadoop is split into multiple Maven modules like Hadoop-common-project, hadoop-hdfs-project, and Hadoop-yarn-project. Running tests for these modules is crucial, especially if you’re fixing a bug or adding a new feature. However, running these tests can be time-consuming. For instance, the hadoop-hdfs-project alone contains over 700 unit tests.

To streamline the testing process, you can use parallel execution, significantly reducing the testing time required. If you need to build Hadoop with a specific patch, you would download and apply the patch to the code and then proceed with the build and test process, possibly adjusting the version number in the pom.xml files to reflect the changes made.

For more detailed guidance on building Hadoop from source, including handling specific build issues and running tests, refer to specialized resources or the official Hadoop documentation.

Hive Bigdata

Hive is a data warehousing tool in the Hadoop ecosystem for processing structured data. It’s designed to simplify and manage large datasets residing in distributed storage. Hive makes querying and analyzing easy, allowing traditional map-reduce programmers to plug in their custom mappers and reducers.

Here’s a brief overview of some key features and aspects of Hive in the context of big data:

SQL-like Language: Hive uses HiveQL (HQL), a language similar to SQL, which makes it easy for those familiar with SQL to query big data.

Storage and Processing: It stores data in the Hadoop Distributed File System (HDFS) and offers ways to query that data. Hive abstracts the complexity of Hadoop, allowing for data summarization, query, and analysis.

Schema on Read: Hive reads data from a database and applies a schema when reading the data.

Compatibility with Hadoop: As part of the Hadoop ecosystem, Hive can process structured data in Hadoop files.

Use Cases: Commonly used for data warehousing tasks like data analysis, large-scale data mining, log processing, and business intelligence.

Extensibility: It supports custom User Defined Functions (UDFs) for tasks like data cleansing, filtering, and complex calculations.

Performance: While Hive provides a convenient SQL interface, it’s sometimes slower than traditional databases, especially for low-latency queries, due to its reliance on MapReduce for data processing.

Community and Ecosystem: Hive is an Apache open-source project with a large community. It integrates well with other technologies in the Hadoop ecosystem.

Remember, Hive is especially beneficial in scenarios where the data warehousing approach and SQL-like querying are needed on top of extensive data systems like Hadoop. However, other tools might be more suitable for real-time processing and analysis.
