Heng Chen created HBASE-14897:
---------------------------------
Summary: TestTableLockManager.testReapAllTableLocks is flakey
Key: HBASE-14897
URL: https://issues.apache.org/jira/browse/HBASE-14897
Project: HBase
Issue Type: Bug
Reporter: Heng Chen
It comes from email list which [~stack] post.
This is the some relates QA information.
https://builds.apache.org/view/H-L/view/HBase/job/HBase-Trunk_matrix/512/jdk=latest1.8,label=Hadoop/testReport/org.apache.hadoop.hbase.master/TestTableLockManager/testReapAllTableLocks/
The reason is here.
{code}
writeLocksObtained.await();
writeLocksAttempted.await();
{code}
writeLocksAttempted maybe count down to 0 before created node on ZK, and main
thread will go on to run lockManager.reapWriteLocks(), And after that node was
created on ZK, so relates lock acquire will timeout.
I upload a patch which can reproduce this issue.
