> 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.
