Difference Between Hadoop and HBase

Hadoop: Hadoop is an open source framework from Apache that is used to store and process large datasets distributed across a cluster of servers. Four main components of Hadoop are Hadoop Distributed File System(HDFS), Yarn, MapReduce, and libraries. It involves not only large data but a mixture of structured, semi-structured, and unstructured information. Amazon, IBM, Microsoft, Cloudera, ScienceSoft, Pivotal, Hortonworks are some of the companies using Hadoop technology. 

HBase: HBase is an open source database from Apache that runs on Hadoop cluster. It falls under the non-relational database management system. Three important components of HBase are HMaster, Region server, Zookeeper. CapitalOne, JPMorganchase, apple, MTB, AT& T, Lockheed Martin are some of the companies using HBase. 

Below is a table of differences between Hadoop and HBase: 

S.No.	Hadoop	HBase
1	Hadoop is a collection of software tools	HBase is a part of hadoop eco-system
2	Stores data sets in a distributed environment	Stores data in a column-oriented manner
3	Hadoop is a framework	HBase is a NOSQL database
4	Data are stored in form of chunks	Data are stored in form of key/value pair
5	Hadoop does not allow run time changes	HBase allows run time changes
6	File can be written only once, can be read many times	File can be read and write multiple times
7	Hadoop has low latency operations	HBase has high latency operations
8	HDFS can be accessed through MapReduce	HBase can be accessed through shell commands, Java API, REST
