------------------------------------
nspiegelberg has commented on the revision "[jira] [HBASE-3690] Option to
Exclude Bulk Import Files from Minor Compaction".
@lhofhansl that's roughly how I changed it. On a per-job basis, you specify
the "hbase.mapreduce.hfileoutputformat.compaction.exclude" parameter. The
reduce phase will embed into the HFiles produced from that job whether to
exclude from minor compaction or not. I put it in the HFile generation stage
instead of the import stage so I wouldn't have to deal with a second file to
persist this metadata.

>
> 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.
