Chris Nauroth updated HDFS-6678:
--------------------------------
Attachment: HDFS-6678.1.patch
The attached patch encloses {{MiniDFSCluster#initMiniDFSCluster}} in a
try-finally. If the full initialization logic in the try block didn't complete
successfully, then the finally block triggers a shutdown of anything that may
have been left running. The patch looks bigger than that just because of
changes in indentation.
> MiniDFSCluster may still be partially running after initialization fails.

> {{MiniDFSCluster}} initializes the daemons (NameNodes, DataNodes) as part of
> object construction. If initialization fails, then the constructor throws an
> exception. When this happens, it's possible that daemons are left running in
> the background. There is effectively no way to clean up after this state,
> because the constructor failed, and therefore the caller has no way to
> trigger a shutdown.
