HBase is accessed through shell commands, Java API, REST, Avro or Thrift API while HDFS is accessed through MapReduce jobs.HBase supports random read and writes while HDFS supports Write once Read Many times.

HBase provides low latency access while HDFS provides high latency operations.

High availability through failover and replication.

Cost-effective from gigabytes to petabytes.

Clients communicate with region servers via zookeeper. It provides services like maintaining configuration information, naming, providing distributed synchronization, server failure notification etc.

Regions of Region Server are responsible for several things, like handling, managing, executing as well as reads and writes HBase operations on that set of regions. Region Server runs on HDFS DataNode which is present in Hadoop cluster. Regions are the basic building elements of HBase cluster that consists of the distribution of tables and are comprised of Column families. HBase Tables are divided horizontally by row key range into Regions. HMaster has many features like controlling load balancing, failover etc. In a distributed environment, Master runs several background threads. It monitor all Region Server instances present in the cluster. It is a process in which regions are assigned to region server as well as DDL (create, delete table) operations. The implementation of Master Server in HBase is HMaster. a secure and easy way to build data pipelines from cloud to on-premises storage locations.
