In-Depth Information
As shown in the preceding diagram, an HBase implementation consists of an HBase mas-
ter node, which is responsible for managing different RegionServers. When a table in
HBase grows in size, it is divided into different regions and is spread across the different
nodes of the cluster. Each node that hosts regions is known as
RegionServer
. HBase re-
lies on ZooKeeper to manage the state of the cluster. All important configuration informa-
tion is stored on the ZooKeeper ensemble. All data for HBase is usually stored in HDFS.
As an administrator, it is very important to know the different components of an HBase
cluster as it helps with faster troubleshooting.
