Eli Collins updated HDFS-4018:

    Attachment: hdfs-4018.txt

Thanks ATM. 

Wrt #1 updated the patch to log the full IOE on failure. Wrt #2, I understand why we check
cluster for null, but per my above comment cluster could never be null here right?

shutdown the cluster if a call to addNameNode fails, so if one of these calls fails other
tests may failed due to the NN directory already being locked.
