Timothy Potter created SOLR-6592:
------------------------------------
Summary: Re-try loop in the
ZkController.waitForLeaderToSeeDownState method hangs unit test when leader is
gone
Key: SOLR-6592
URL: https://issues.apache.org/jira/browse/SOLR-6592
Project: Solr
Issue Type: Bug
Reporter: Timothy Potter
HttpPartitionTest is failing due to a ThreadLeakError, which I believe is
because the re-try loop in ZkController.waitForLeaderToSeeDownState is coded to
take upwards of 12 minutes to fail (2 minutes socket timeout, 6 max retries).
The code should be improved to stop trying if the leader is gone, which seems
to be the case here (maybe). At the very least, need to figure out how to avoid
this ThreadLeakError.
