>                 URL: https://issues.apache.org/jira/browse/HBASE-23832
>             Project: HBase
>          Issue Type: Bug
>    Affects Versions: 2.0.0
>            Reporter: Anoop Sam John
>            Assignee: Sambit Mohapatra
>            Priority: Critical
>             Fix For: 3.0.0-alpha-1, 2.3.0, 2.1.10, 2.2.5

> 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.
