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: org.apache.hadoop.mapreduce.v2.app.MRAppMaster at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:252) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320) Could not find the main class: org.apache.hadoop.mapreduce.v2.app.MRAppMaster.
