Anoop Sam John commented on HBASE-22380:
----------------------------------------

Why the client to pass the clusterId in RPC?  The original RS can add the 
clusterId into the special WAL cell and thus make it be passed to the next 
cluster right?  Only passing the original (first) clusterId is enough?  What if 
a flow  like clusterA -> clusterB <->  clusterC ?

> break circle replication when doing bulkload
