Hadoop is a big data platform that is being used by the companies to store huge amounts of data. It is a reliable tool for big data analytics and machine learning.
Apache Hadoop is a free software framework for storing, managing, and processing large amounts of data. It is an open source implementation of MapReduce, an algorithm for parallel distributed computation, developed at the University of California, Berkeley. The most famous open-source implementation of MapReduce is the Google File System (GFS). Apache Hadoop is mainly used for handling big data sets. Apache Hadoop is very useful for analyzing huge data sets. It provides a robust environment to perform complex data analytics.
Apache Hadoop is the most efficient solution for dealing with big data. Data Scientists need to analyze vast amount of data to find patterns in it. They use Hadoop to run MapReduce algorithms to analyze the data. In Hadoop, each task is divided into multiple chunks, and each chunk is processed by a single node. Each node has a master that runs a program called a mapper. The mapper is designed to extract information from the data.
The next step is to run the mapper in a loop over the data, which is stored as a sequence of key-value pairs. The value of a key is the value of the mapper, and the key is the location of the data. After all the mappers have been executed, the results are combined and sent to the reducer.
The reducer is a program that takes all the output from the mappers and combines it to form a single output. The output can be written to a file or another system for further analysis.
The main components in Hadoop:
- Hadoop Distributed File System (HDFS): HDFS is a distributed file system. It is the basic component of Hadoop and consists of a storage layer and a network layer. The storage layer consists of a number of servers that store the files. The network layer consists of several machines that act as servers. These servers are connected to each other through a high-speed network.
- Hadoop Yarn: YARN is the core service of Hadoop. YARN consists of two parts: Resource Manager and Node Manager. The Resource Manager is the program that manages the resources like RAM, CPU, and storage. The Node Manager is the program that manages the Hadoop jobs.
- Apache HBase: Apache HBase is the database engine of Hadoop. It supports Big Data applications that require fast access to the data.
- Apache Hive: Apache Hive is the interface to store and query data in a database. Apache Hive supports different languages like SQL and Pig Latin.
- Apache Oozie: Apache Oozie is the workflow scheduler for Hadoop.
- Apache Sqoop: Apache Sqoop is the bridge between Hadoop and other databases. It connects Hadoop to a relational database.
- Apache Flume: Apache Flume is a framework that collects and stores events from different sources like web, mail, etc.
- Apache Zookeeper: Apache Zookeeper is a distributed, highly-available, and reliable service.
- Apache Giraph: Apache Giraph is a framework that helps in analyzing graphs. It is developed by Yahoo and has a similar functionality to Apache Mahout.
- Apache Spark: Apache Spark is a framework that helps in machine learning, graph analysis, and data mining.

20. Apache Oozie
Apache Oozie – The Best Workflow Solution
Oozie is a workflow solution provided by Apache Hadoop. The name is derived from the combination of the words “O” for Oozie and “Hadoop”. Apache Oozie is the workflow manager that is used to execute the workflow defined in Hadoop. Oozie works on the YARN cluster.
Oozie provides two main features:
- Workflow management
- Automation and orchestration
Workflow management:
Workflows are nothing but a series of actions that are executed in sequence. It is the most basic form of automation. A workflow is nothing but a set of tasks that are repeated again and again. In this context, a workflow can be executed as a unit and not as a sequence of tasks.
Automation and orchestration:
In automation and orchestration, there is an objective to complete a task in a predefined manner. The task is usually a complex job or a task that is performed over multiple nodes.
Oozie provides two types of workflow:
- Sequential workflow
- Parallel workflow
Sequential workflow
A sequential workflow is nothing but a series of tasks that are executed in a predefined order. The workflow is very similar to a workflow in Hadoop MapReduce.
Parallel workflow:
A parallel workflow is nothing but a set of parallel tasks that are executed in a predefined manner. In this context, parallel means that each task is executed in a different node.
Oozie provides three ways of workflow execution:
- Spark
- Flume
- S4
Spark: Spark is a distributed engine that executes a workflow by splitting the tasks and executing it in a distributed manner. Spark is the best option when you are dealing with large volumes of data and need to process a large amount of data in a short period of time.
Flume: Flume is a distributed engine that executes a workflow by storing the data in a distributed manner. It is a batch-oriented system and is used to collect and store data. Flume is an open source and is very similar to Flume.
S4: S4 is a serverless workflow engine. It is an open source workflow engine that can be easily integrated in your existing applications. S4 is the simplest option for executing a workflow and it is the most preferred option for a developer.
Oozie provides two main interfaces:
- Command-line interface: This is the most common way for developers to interact with Oozie.
- Web interface: The web interface is a graphical user interface that allows you to control the Oozie server.
Oozie is mainly used for the following:
- Workflow scheduling
- Data processing
- Distributed application development
- Cloud based application development
Here, discussed about the workflow solutions provided by Apache Oozie. We hope this will help you to understand the workflow solutions in a better way.
