> AMS HBase FIFO compaction policy and Normalizer settings are not handled correctly.
> A user could change the defaults for these settings via configuration updates but at least two problems would result. 
> 1) Updates to variables AMS_HBASE_FIFO_COMPACTION_ENABLED and AMS_HBASE_NORMALIZER_ENABLED will not be honored.  Same would be the case for the recent addition to ams-env  - AMS_HBASE_INIT_CHECK_ENABLED.
> 2) During upgrade to Ambari 2.2.0 these settings will not be correctly handled due to incorrect variable names and leads to exceptions e.g if AMS_HBASE_FIFO_COMPACTION_ENABLED  was expected to be set to 'false', for instance if the AMS HBase version did not support FIFO compaction policy.
