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

             Summary: Old config hbase.hstore.compactionThreshold is ignored
                 Key: HBASE-23832
                 URL: https://issues.apache.org/jira/browse/HBASE-23832
             Project: HBase
          Issue Type: Bug
            Reporter: Anoop Sam John


In 2.x we added new name 'hbase.hstore.compaction.min' for this.  Still for compatibility we allow the old config name and honor that in code
{code}
minFilesToCompact = Math.max(2, conf.getInt(HBASE_HSTORE_COMPACTION_MIN_KEY,
          /*old name*/ conf.getInt("hbase.hstore.compactionThreshold", 3)));
{code}
But if hbase.hstore.compactionThreshold alone is configured by user, there is no impact of that.
This is because in hbase-default.xml we have the new config with a value of 3. So the call conf.getInt(HBASE_HSTORE_COMPACTION_MIN_KEY) always return a value 3 even if it is not explicitly configured by customer and instead used the old key.
