Description

I saw the following when trying to determine startup failure:

2014-01-21 06:07:17,871 FATAL [master:h2-centos6-uns-1390276854-hbase-10:60000] master.HMaster: Unhandled exception. Starting shutdown.

Property name should be included in the following exception:

    Preconditions.checkArgument(
        value != null,
        "Property value must not be null");
