Description
Looking into parent issue, got a hang locally of TestDistributedLogReplay.
We have region closes here:
"RS_CLOSE_META-localhost:59610-0" prio=5 tid=0x00007ff65c03f800 nid=0x54347 waiting on condition [0x000000011f7ac000] java.lang.Thread.State: WAITING (parking) at sun.misc.Unsafe.park(Native Method) - parking to wait for <0x000000075636d8c0> (a java.util.concurrent.locks.ReentrantReadWriteLock$NonfairSync) at java.util.concurrent.locks.LockSupport.park(LockSupport.java:186) at java.util.concurrent.locks.AbstractQueuedSynchronizer.parkAndCheckInterrupt(AbstractQueuedSynchronizer.java:834) at java.util.concurrent.locks.AbstractQueuedSynchronizer.acquireQueued(AbstractQueuedSynchronizer.java:867) at java.util.concurrent.locks.AbstractQueuedSynchronizer.acquire(AbstractQueuedSynchronizer.java:1197) at java.util.concurrent.locks.ReentrantReadWriteLock$WriteLock.lock(ReentrantReadWriteLock.java:945) at org.apache.hadoop.hbase.regionserver.MetricsRegionAggregateSourceImpl.deregister(MetricsRegionAggregateSourceImpl.java:78) at org.apache.hadoop.hbase.regionserver.MetricsRegionSourceImpl.close(MetricsRegionSourceImpl.java:120) at org.apache.hadoop.hbase.regionserver.MetricsRegion.close(MetricsRegion.java:41) at org.apache.hadoop.hbase.regionserver.HRegion.doClose(HRegion.java:1500) at org.apache.hadoop.hbase.regionserver.HRegion.close(HRegion.java:1344) - locked <0x00000007ff878190> (a java.lang.Object) at org.apache.hadoop.hbase.regionserver.handler.CloseRegionHandler.process(CloseRegionHandler.java:102) at org.apache.hadoop.hbase.executor.EventHandler.run(EventHandler.java:103) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:744)
They are trying to MetricsRegionAggregateSourceImpl.deregister. They want to get a write lock on this classes local ReentrantReadWriteLock while holding MetricsRegionSourceImpl's readWriteLock write lock.
Then, elsewhere the JmxCacheBuster is running trying to get metrics with above locks held in reverse:
