Eric Payne commented on MAPREDUCE-3393:
---------------------------------------
Just a few updates:
# For the error: 'Problem binding to [0.0.0.0:8025] java.net.BindException:
Address already in use; For more details see'
One of the tests in hadoop-mapreduce-client-jobclient seems to be hanging
around after it is done. It hangs on to port 8025 so later tests can't bind to
that port.
# For the TestMROldApiJobs failure ({{mvn -Dtest=TestMROldApiJobs test}}):
I can consistently reproduce this one, even if I run only that test. It is
getting a ClassNotFoundException:
{noformat}
Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/hadoop/mapreduce/v2/app/MRAppMaster
Caused by: java.lang.ClassNotFoundException:

Could not find the main class: org.apache.hadoop.mapreduce.v2.app.MRAppMaster.
Program will exit.
{noformat}
In order to view the above output, I had to find the {{stderr}} file for the
application container that failed during the unit test.
