> Over in HBASE-16349, [~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:

> It turned out that htd for hbase:namespace table was null.
> Once the NPE is fixed, the test passes.
