--------------------------------------
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.
