Subject [jira] [Created] (AMBARI-15331) AMS HBase FIFO compaction policy and Normalizer settings are not handled correctly
Date Tue, 08 Mar 2016 04:34:40 GMT

-----------------------------------------

             Summary: AMS HBase FIFO compaction policy and Normalizer settings are not handled
correctly
                 Key: AMBARI-15331
                 URL: https://issues.apache.org/jira/browse/AMBARI-15331
             Project: Ambari
          Issue Type: Bug
          Components: ambari-metrics
    Affects Versions: 2.2.0
            Reporter: Shantanu Mundkur
            Assignee: Shantanu Mundkur
             Fix For: trunk, 2.4.0


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.
