Use default mode for HBase Thrift gateway if not specified
hbase-thrift cannot be started properly
Would be awesome to have this in 0.6.0
HBASE-6263 was fixed in HBase 0.94.2, and current Bigtop HBase version is 0.94.5, so this fix makes sense at this point.
Patch is attached. Tested on CentOS 6.2.
+1 and committed!
