I have 2 hbase cluster named A and B , each cluster have 3 machines, i want to enable replication between the 2 cluster, here is the step
-
add config to hbase-site.xml
hbase.replication true
-
in master cluster A, add peer
add_peer '2',"wxmaster1,wxmaster2,wxslave1:2181:/hbase2"
this return success, as I can see in log , cluster A master log have init the session connection to cluster B regionservers.
-
create the same table in cluster A and B
create 'test_replication', {NAME => 'cf', REPLICATION_SCOPE => '1', VERSIONS => '2', KEEP_DELETED_CELLS => 'TRUE'}
then I think everything should be ok, any change at cluster A table 'test_replication' will copy to cluster B, while it not, and no any error log.
-
here is the results for status 'replication' enter image description here
