-----------------------------------------
Summary: Junit in TestJobHistoryServer failing in jdk 7
Key: MAPREDUCE-5425
URL: https://issues.apache.org/jira/browse/MAPREDUCE-5425
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: jobhistoryserver
Affects Versions: 2.0.4-alpha
Reporter: Ashwin Shankar
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.
