> 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:

> 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.
