Subject [jira] [Commented] (HBASE-13153) Bulk Loaded HFile Replication

Devaraj Das commented on HBASE-13153:
-------------------------------------

Ashish, nice work. One question - when the peer cluster does a bulkload, I am wondering if
the network is slow, would it hold up the peer RegionServer handlers for a longer duration
for bigger bulkloads, and thereby affect the throughput of the peer cluster significantly.

> 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
