dtm.HBaseTxClient throws NullException

[Matt Brown]

See the following on both single node and multi-node platforms in the monitor log. Appears after "sqstart" is executed

When there is no object returned by zookeeper.checkForRecovery(), we will see this nullPointerException error.

A simple fix can be to do an 'if (regions != null) { // print message};'

Good catch!
