Robert Parker updated MAPREDUCE-5425:
-------------------------------------
Attachment: MAPREDUCE-5425.patch
Modified the JobHistoryServer.main() to call a package scoped static function
that contains the previous contents of main. This allows the testMain test to
call the static function that returns a historyServer instance that can be
shutdown. The testMain test was not being shutdown and was running first in
JDK7 which caused the other tests to fail.
> Junit in TestJobHistoryServer failing in jdk 7

> 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
> at org.apache.hadoop.net.NetUtils.wrapException(NetUtils.java:719)
> at org.apache.hadoop.ipc.Server.bind(Server.java:423)
> at org.apache.hadoop.ipc.Server$Listener.<init>(Server.java:535)

> org.apache.hadoop.service.AbstractService.init(AbstractService.java:163)
> 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.
