Description

TestHsWebServicesJobsQuery fails on jdk7 due to the test order no longer being constant.

testJobsQueryStateNone(org.apache.hadoop.mapreduce.v2.hs.webapp.TestHsWebServicesJobsQuery) Time elapsed: 0.279 sec <<< FAILURE!

It looks like the issues is that the mock jobs just iterate through the JOBSTATE and since other tests run first we just happen to hit the state KILL_WAIT that we don't expect any jobs to be in.
