Hadoop is an open-source distributed processing software framework and is made up of "modules" like any other framework.Each moduleperforms a specific task necessary for a processing system intended for big data analytics. Hadoop framework accomplishes data processing and storage for big data applications running in clustered systems. The term "Hadoop" is commonly used for all ecosystem which runs on HDFS.
Hadoop Distributed File System (HDFS) - which allows data storage in an effortlesslyavailablelayout, across a large number of connected storage devices.
Map Reduce is termed after the two basic tasks this module carries out - reading data from the database, putting it into a format suitable for analysis (map), and executing mathematical operations.
Hadoop Common offers the tools (in Java) desired for the user's computer systems (Windows, UNIX or whatever) to read data stored under the Hadoop file system.
The final module YARN, handles resources of the systems storing the data and running the analysis.
ZooKeeper is anintegrated service for maintaining configuration information, naming, providing distributed management, and providing group services. These services are used in some way or the other by distributed applications.
Hadoop is not a programming language neither a type of database, but rather a software ecosystem that allows enormous simultaneous computing It enables certain types NoSQL spreaded databases (such as HBase), which allows for data to be spread across thousands of servers with little variation in performance.
Learning Hadoop is not very difficult. Hadoop is a framework of java. Java is not a compulsory prerequisite for learning Hadoop (as in HDFS + Map Reduce) but to really understand and use it you'll need to learn Java/Python.
