-------------------------------------

             Summary: Runtime NullPointerException in MiniDFSCluster on CentOS and other Linux
                 Key: HBASE-8944
                 URL: https://issues.apache.org/jira/browse/HBASE-8944
             Project: HBase
          Issue Type: Bug
    Affects Versions: 0.94.6.1, 0.94.6
            Reporter: David Williams


The HBaseTestingUtility appears to have an unhandled NullPointerException in certain environments.   It works on Apache HBase 0.94.6.1 on Mac OSX but not in certain Linux environments such as CentOS. 

In Java:
{code}
HBaseTestingUtility testingUtility = new HBaseTestingUtility();
testingUtility.startMiniCluster(1);  // blows up on Linux but not Mac OSX
{code}

Creates this exception:
{code}
ERROR in (create-table) (MiniDFSCluster.java:426)
Uncaught exception, not in assertion.
expected: nil
  actual: java.lang.NullPointerException: null
