Question - What does replication mean in terms of HBase?
Answer -
The replication feature in HBase provides a mechanism to copy data between clusters. This feature can be used as a disaster recovery solution that provides high availability for HBase.
The following commands alter the hbase1 table and set the replication_scope to 1. A replication_scope of 0 indicates that the table is not replicated.
disable ‘hbase1’
alter ‘hbase1’, {NAME => ‘family_name’, REPLICATION_SCOPE => ‘1’}
enable ‘hbase1’
