Auto-HA: TestZKFailoverControllerStress occasionally fails with Mockito error
-----------------------------------------------------------------------------
Key: HADOOP-8257
URL: https://issues.apache.org/jira/browse/HADOOP-8257
Project: Hadoop Common
Issue Type: Bug
Components: auto-failover, test
Affects Versions: Auto Failover (HDFS-3042)
Reporter: Todd Lipcon
Assignee: Todd Lipcon
Priority: Trivial
Attachments: hadoop-8257.txt
Once in a while I've seen the following in TestZKFailoverControllerStress:
Unfinished stubbing detected here: -> at
org.apache.hadoop.ha.TestZKFailoverControllerStress.testRandomHealthAndDisconnects(TestZKFailoverControllerStress.java:118)
E.g. thenReturn() may be missing....
This is because we set up the mock answers _after_ starting the ZKFCs. So if
the ZKFC calls the mock object while it's in the middle of the setup, this
exception occurs.
