> We ran an incremental scrape with HFileOutputFormat and encountered major compaction
storms.  This is caused by the bug in HBASE-3404.  The permanent fix is a little tricky without
HBASE-2856.  We realized that a quicker solution for avoiding these compaction storms is to
simply exclude bulk import files from minor compactions and let them only be handled by time-based
major compactions.  Add with functionality along with a config option to enable it.
