Zheng Hu commented on HBASE-20148:
----------------------------------

+1, Skimmed the patch,  it's simple and elegant.  Need to add a shell command for turning
non-serial peer to be a serial peer.  Can do this in a separate jira ..

> Discussed with [~zghaobac] and [~openinx] offline, HBASE-20147 can only be solved by
adding new stages when creating a new replication peer. It will also effect he processing
even if you do not have any table with serial replication. And also, the new logic introduced
in ReplicationSource related classes will also be executed even if you do not have serial
replication tables.
> So, we think that it maybe a better choice to move the option to ReplicationPeerConfig.
Since if there is one table in the peer requires serial replication, then all the tables in
this peer will be automatically 'serial' since the wal for these tables are mixed with the
one which requires serial replication.
