Apache HBase Replication allows you to copy data from one HBase cluster to a different
and possibly distant HBase cluster. This can be used for disaster recovery or when you want to
run load intensive MapReduce jobs on your HBase cluster.
-
For every existing table, set the
REPLICATION_SCOPE on every column
family that you want to index:
hbase shell
hbase shell> disable 'sample_table'
hbase shell> alter 'sample_table', {NAME => 'columnfamily1', REPLICATION_SCOPE => 1}
hbase shell> enable 'sample_table'
-
For every new table, set the
REPLICATION_SCOPE on every column family
that you want to index using a command such as the following:
hbase shell
hbase shell> create 'test_table', {NAME => 'testcolumnfamily', REPLICATION_SCOPE => 1}
