Subject [jira] [Commented] (HBASE-13153) enable bulkload to support replication
Date Wed, 02 Sep 2015 16:31:46 GMT

Ted Yu commented on HBASE-13153:
--------------------------------

bq. and after a successful notification about this hfiles to its peer clusters

There seem to be two types of notifications from the peer cluster: one which signifies the
success of load in the immediate peer cluster and one which signifies the success of load
from downstream peer clusters. Is that right ?
What if the second type of notification is lost due to network glitch ?

> Currently we plan to use HBase Replication feature to deal with disaster tolerance scenario.But
we encounter an issue that we will use bulkload very frequently,because bulkload bypass write
path, and will not generate WAL, so the data will not be replicated to backup cluster. It's
inappropriate to bukload twice both on active cluster and backup cluster. So i advise do some
modification to bulkload feature to enable bukload to both active cluster and backup cluster
