             Summary: RSRpcServices#openRegion() should handle the case where table descriptor is null
                 Key: HBASE-16830
                 URL: https://issues.apache.org/jira/browse/HBASE-16830

            Reporter: Ted Yu
            Assignee: Ted Yu


[~mantonov] pointed me to the failed TestClusterId in Jenkins 1.3 build.
I ran the test locally with Java 8 and consistently stumbled over timeout in starting the mini cluster:
{code}

{code}
It turned out that htd for hbase:namespace table was null.

Once the NPE is fixed, the test passes.
