Andrew Purtell resolved HBASE-5161.
-----------------------------------
Resolution: Incomplete
Fix Version/s: (was: 0.92.1)
> Compaction algorithm should prioritize reference files
> ------------------------------------------------------
>
> Key: HBASE-5161
> URL: https://issues.apache.org/jira/browse/HBASE-5161
> Project: HBase
> Issue Type: Bug
> Affects Versions: 0.92.0
> Reporter: Jean-Daniel Cryans
> Priority: Critical
>
> I got myself into a state where my table was un-splittable as long as the
> insert load was coming in. Emergency flushes because of the low memory
> barrier don't check the number of store files so it never blocks, to a point
> where I had in one case 45 store files and the compactions were almost never
> done on the reference files (had 15 of them, went down by one in 20 minutes).
> Since you can't split regions with reference files, that region couldn't
> split and was doomed to just get more store files until the load stopped.
> Marking this as a minor issue, what we really need is a better pushback
> mechanism but not prioritizing reference files seems wrong.
