> Concurrency issue in WAL unflushed seqId tracking

>
> Key: HBASE-16721

> Project: HBase
> Issue Type: Bug

> Reporter: Enis Soztutar

> I'm inspecting an interesting case where in a production cluster, some
> regionservers ends up accumulating hundreds of WAL files, even with force
> flushes going on due to max logs. This happened multiple times on the
> cluster, but not on other clusters. The cluster has periodic memstore flusher
> disabled, however, this still does not explain why the force flush of regions
> due to max limit is not working. I think the periodic memstore flusher just
> masks the underlying problem, which is why we do not see this in other
> clusters.
> The problem starts like this:
> {code}
> 2016-09-21 17:49:18,272 INFO [regionserver//10.2.0.55:16020.logRoller]
> wal.FSHLog: Too many wals: logs=33, maxlogs=32; forcing flush of 1
> regions(s): d4cf39dc40ea79f5da4d0cf66d03cb1f
> 2016-09-21 17:49:18,273 WARN [regionserver//10.2.0.55:16020.logRoller]
> regionserver.LogRoller: Failed to schedule flush of
> d4cf39dc40ea79f5da4d0cf66d03cb1f, region=null, requester=null
> {code}
> then, it continues until the RS is restarted:
> {code}
> 2016-09-23 17:43:49,356 INFO [regionserver//10.2.0.55:16020.logRoller]
> wal.FSHLog: Too many wals: logs=721, maxlogs=32; forcing flush of 1
> regions(s): d4cf39dc40ea79f5da4d0cf66d03cb1f
> 2016-09-23 17:43:49,357 WARN [regionserver//10.2.0.55:16020.logRoller]
> regionserver.LogRoller: Failed to schedule flush of
> d4cf39dc40ea79f5da4d0cf66d03cb1f, region=null, requester=null
> {code}
> The problem is that region {{d4cf39dc40ea79f5da4d0cf66d03cb1f}} is already
> split some time ago, and was able to flush its data and split without any
> problems. However, the FSHLog still thinks that there is some unflushed data
> for this region.
