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?
