Subject [jira] Commented: (HBASE-938) major compaction period is not checked periodically
Date Mon, 20 Oct 2008 02:56:44 GMT

Rong-En Fan commented on HBASE-938:
-----------------------------------

In a ~400 regions cluster, I see 140 major compaction within 40 mins after I started the cluster,
and this is still on-going.

> The major compaction period, hbase.hregion.majorcompaction, is not checked periodically.
Currently, we only request major compaction when the region is open or split at which point
we check whether the major compaction period is due.
