Ted Yu commented on HBASE-17290:

Test failure was caused by:
Caused by: java.lang.NullPointerException
	at org.apache.hadoop.hbase.replication.TestMasterReplication.startMiniClusters(TestMasterReplication.java:492)

Please fix in the next patch.

> Currently the support for replication of bulk loaded hfiles relies on bulk load marker
written in the WAL.
> The move of bulk loaded hfile(s) (into region directory) may succeed but the write of
bulk load marker may fail.
> This means that although bulk loaded hfile is being served in source cluster, the replication
wouldn't happen.
> Normally operator is supposed to retry the bulk load. But relying on human retry is not
robust solution.
