Xiao Chen updated HADOOP-12715:
-------------------------------
Attachment: HADOOP-12715.01.patch
Reason for the failure is because {{ValueQueue}} has an async filling thread.
There's a race between the async filling after {{getAtMost(10)}}, and the sync
filling of {{getAtMost(19)}}.
Patch 1 enhanced the test to first check the async {{getAtMost(10)}}, then
check the sync {{getAtMost(19)}}. Also added timeout to all tests in this
class, and enhanced the asserts to have a message.
> TestValueQueue#testgetAtMostPolicyALL fails intermittently
