HBASE

HBase is a column-oriented non-relational database management system that runs on HDFS. 

HBase columns are defined by column families. 

HBase is linearly scalable, highly efficient and provides an easy-to-use Java API for client 

access. 

A key difference between HDFS and HBase is that HBase allows dynamic changes compared 

to the rigid architecture of HDFS 

HBase architecture consists of HMaster, Region servers, Region, Zookeeper and HDFS.
