Description

I was looking at, pre-commit builds: https://builds.apache.org/job/oozie-trunk-precommit-build/

Most of the times, the build is failing due to failure of following 2 test cases:
==============================================================
org.apache.oozie.event.TestEventGeneration.testForNoDuplicates (see OOZIE-2429)
org.apache.oozie.util.TestMetricsInstrumentation.testSamplers

Every time, these test cases fail with the same error and I feel, they need to be fixed.

org.apache.oozie.util.TestMetricsInstrumentation.testSamplers
==============================================================
