MiniMRCluster does not start correctly.
---------------------------------------
Key: MAPREDUCE-2163
URL: https://issues.apache.org/jira/browse/MAPREDUCE-2163
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: test
Affects Versions: 0.22.0
Reporter: Mithun Radhakrishnan
Test code written against MiniMRCluster does not execute correctly. The
MiniDFSCluster instance comes up alright, but when the MiniMRCluster starts up,
one gets hundreds of stack-traces of the following kind:
10/10/28 15:55:47 INFO ipc.Server: IPC Server handler 2 on 61176, call

It would appear that the hadoop-mapred-test-0.22.0-SNAPSHOT.jar hosted on
Apache might be missing the srcChecksum element, wherever
HadoopVersionAnnotation is being used.
