HIVE-3179: HBase Handler doesn't handle NULLs properly
Review Request #5542 - Created June 25, 2012 and updated
This patch moves the initialization of the fieldsInited variable to the end of the loop because otherwise NULL values will return stale data on the second iteration. All other cases should be unaffected by this change.
Debugged problem, added code to existing test to force wrong behavior which is fixed by this patch, ran the hbase-handler unit tests
