[jira] [Created] (HBASE-8944) Runtime NullPointerException in
MiniDFSCluster on CentOS and other Linux
David Williams created HBASE-8944:
-------------------------------------
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
