Todd Lipcon updated HADOOP-8204:
--------------------------------
Attachment: hadoop-8204.txt
Attached patch is on top of HADOOP-8193 and fixes the issue.
The problem was that you can't concurrently call mocks and set up mock behavior
in Mockito. So the health monitor would occasionally call the mock proxy at the
same time as the test case was changing the behavior of the mock proxy.
The fix is to pull some of the patch for HDFS-2185 into this one: HealthMonitor
now monitors an HAServiceTarget, and the test implementation of HAServiceTarget
has code to trigger different failure scenarios. The test now passes reliably
for me.
