      Description

      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)
      + Victor Xu 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?
