Date Wed, 19 Feb 2014 20:37:29 GMT

     [ https://issues.apache.org/jira/browse/HDFS-5742?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Arpit Agarwal updated HDFS-5742:
--------------------------------

    Description: 
DatanodeCluster fails to start with NPE in MiniDFSCluster.

Looks like a simple bug in {{MiniDFSCluster#determineDfsBaseDir}} - missing check for null
configuration.

Also included are a few improvements to DataNodeCluster, details in comments below.
