[replication] ReplicationSink can deadlock itself via handlers
--------------------------------------------------------------
Key: HBASE-4280
URL: https://issues.apache.org/jira/browse/HBASE-4280
Project: HBase
Issue Type: Improvement
Affects Versions: 0.90.4
Reporter: Jean-Daniel Cryans
Assignee: Jean-Daniel Cryans
Fix For: 0.90.5
I've experienced this problem a few times, ReplicationSink calls are received
through the normal handlers and potentially can call itself which, in certain
situations, call fill up all the handlers. For example, 10 handlers that are
all replication calls are all trying to talk to the local server at the same
time.
HRS.replicateLogEntries should have @QosPriority(priority=HIGH_QOS) to use the
other set of handlers.
