> Key: HBASE-8663
> URL: https://issues.apache.org/jira/browse/HBASE-8663
> Project: HBase
> Issue Type: New Feature
> Components: Replication, shell
> Environment: clusters setup as Master and Slave for replication of
> tables
> Reporter: Demai Ni
> Assignee: Demai Ni
> Priority: Critical
> Attachments: HBASE-8663.PATCH, HBASE-8663-trunk-v0.patch,

>
> This jira is to provide a hbase shell command which can give user can
> overview of the tables/columnfamilies currently being replicated. The
> information will help system administrator for design and planning, and also
> help application programmer to know which tables/columns should be
> watchout(for example, not to modify a replicated columnfamily on the slave
> cluster)
> Currently there is no easy way to tell which table(s)/columnfamily(ies)
> replicated from or to a particular cluster.
>
> On Master Cluster, an indirect method can be used by combining two steps: 1)
> $describe 'usertable' and 2) $list_peers to map the REPLICATION_SCOPE to
> target(aka slave) cluster
>
> On slave cluster, this is no existing API/methods to list all the tables
> replicated to this cluster.
> Here is an example, and prototype for Master cluster
> {code: title=hbase shell command:list_replicated_tables |borderStyle=solid}
> hbase(main):001:0> list_replicated_tables
> TABLE COLUMNFAMILY TARGET_CLUSTER
> scores course hdtest017.svl.ibm.com:2181:/hbase
