Wellington Chevreuil updated HBASE-28724:
-----------------------------------------
Affects Version/s: 3.0.0
> BucketCache.notifyFileCachingCompleted may throw IllegalMonitorStateException
> ------------------------------------------------------------------------------
>
> Key: HBASE-28724
> URL: https://issues.apache.org/jira/browse/HBASE-28724
> Project: HBase
> Issue Type: Bug
> Affects Versions: 3.0.0
> Reporter: Wellington Chevreuil
> Assignee: Wellington Chevreuil
> Priority: Major
>
> If the prefetch thread completes reading the file blocks faster than the
> bucket cache writer threads are able to drain it from the writer queues, we
> might run into a scenario where BucketCache.notifyFileCachingCompleted may
> throw IllegalMonitorStateException, as we can reach [this block of the
> code|https://github.com/wchevreuil/hbase/blob/684964f1c1693d2a0792b7b721c92693d75b4cea/hbase-server/src/main/java/org/apache/hadoop/hbase/io/hfile/bucket/BucketCache.java#L2106].
> I believe the impact is not critical, as the prefetch thread is already
> finishing at that point, but nevertheless, such error in the logs might be
> misleading.
