> a HBase Shell command to list the tables replicated from current cluster

> Thanks for the discussion and very good suggestions,I'd reduce the scope of
> this jira to only display the tables replicated from current cluster. Since
> currently no good(accurate and consistent) way to flag a table on slave
> cluster, this jira will not cover such scenario. Instead, the patch will be
> flexible enough to adapt such scenario and a follow up JIRA will be opened to
> address such situation.
> The shell command and output will be like. Since all replication is 'global',
> so no need to display the cluster name here. In the future, the command will
> be extended for other scenarios, such as 1) replicated only to selected peers
> or 2) indicate table:colfam on slave side
> {code: title=hbase shell command:list_replicated_tables |borderStyle=solid}
> hbase(main):001:0> list_replicated_tables
> TABLE:COLUMNFAMILY ReplicationType
>
> t1_dn:cf1 GLOBAL
>
> t2_dn:cf2 GLOBAL
>
> usertable:family GLOBAL
>
> 3 row(s) in 0.4110 seconds
> hbase(main):003:0> list_replicated_tables "dn"
> TABLE:COLUMNFAMILY ReplicationType
>
> t1_dn:cf1 GLOBAL

> {code}
> -------------- The original JIRA description, keep as the history of
> discussion ---------------
> 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
