HBase – A NoSQL DataBase
Basically, a non-relational column-oriented distributed database which runs on top of HDFS is what we call HBase. It stores data in rows and columns and also a NoSQL open source database.In addition, versioning makes it possible to retrieve any version of contents in order to track changes in the cell. Here, each cell value has a “version” attribute, that is nothing more than a timestamp identifying the cell. where each value in the map is an uninterrupted array of bytes.
However, learn more about HBase in detail, follow the link: Apache HBase Tutorial For Beginners 2018
Components of HBase Architecture
HBase components are:– HMaster- it handles negotiating load balancing across all Region Servers as well as it maintains the state of the Hadoop cluster.
– RegionServer- It is a node which is deployed on each machine and hosts data and processes I/O requests.
– ZooKeeper- It is an open-source server that enables reliable distributed coordination.However, learn more about HBase components in detail, follow the link: HBase Architecture – Regions, Hmaster, Zookeeper
