Description

We get the following exception when we run the unit tests of TestJobHistoryServer with jdk 7:
Caused by: java.net.BindException: Problem binding to [0.0.0.0:10033] java.net.BindException: Address already in use; For more details see: http://wiki.apache.org/hadoop/BindException

This is happening because testMainMethod starts the history server and doesnt stop it. This worked in jdk 6 because tests executed sequentially and this test was last one and didnt affect other tests,but in jdk 7 it fails.
