---------------------------------
Summary: Should add backoff when replaying failed in
SyncReplicationReplayWALProcedure
Key: HBASE-21539
URL: https://issues.apache.org/jira/browse/HBASE-21539
Project: HBase
Issue Type: Sub-task
Reporter: Duo Zhang
I'm still testing serial&sync replication and it is stuck again...
Still need to find out the root cause but there is another problem, since the
replication is stuck, we have lots of wals to replay, and cause too much
pressure on the memstore and the region rejects the write requests so the
SyncReplicationReplayWALRemoteProcedure fails. But soon we will schedule a new
SyncReplicationReplayWALRemoteProcedure without any sleeps, which means we are
keep adding pressure to the memstore. The result is very clear, we can not
finish the replay, and write too much duplicated data to the region, and can
not recover any more...
