Subject [jira] [Commented] (HBASE-11368) Multi-column family BulkLoad fails if compactions go on too long

> Compactions take a read lock.  If a multi-column family region, before bulk loading,
we want to take a write lock on the region.  If the compaction takes too long, the bulk load
fails.
> Various recipes include:
> + Making smaller regions (lame)
> + [~victorunique] suggests major compacting just before bulk loading over in HBASE-10882
as a work around.
> Does the compaction need a read lock for that long?  Does the bulk load need a full write
lock when multiple column families?  Can we fail more gracefully at least?
