             Summary: BucketCache.notifyFileCachingCompleted may throw IllegalMonitorStateException 
                 Key: HBASE-28724
                 URL: https://issues.apache.org/jira/browse/HBASE-28724
             Project: HBase
          Issue Type: Bug
            Reporter: Wellington Chevreuil
            Assignee: Wellington Chevreuil


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.
