Description

Problem:
When tables are created dynamically in Hbase cluster, the Replication feature can't be used as the new table does not exist in peer cluster. To use the replication, we need to create same table in peer cluster also.

Having API to replicate the create table statement at peer cluster will be more helpful in such cases.

Solution:

create 'table','cf',replication => true , peerFlag => true

if peerFlag = true, the table with the column family has to be created at peer
cluster.

Special cases like enabling replication at peer cluster also for cyclic replication has to be considered.
