Jean-Daniel Cryans commented on HBASE-1947:
-------------------------------------------
Ryan reviewed this patch and wants me to clear the compaction message. I will
commit the same patch but with:
{code}
- // Startup a compaction early if one is needed, if region has
references.
- if (region.hasReferences()) {
+ // Startup a compaction early if one is needed, if region has
references
+ // or it a store has too many store files
+ if (region.hasReferences() || region.hasTooManyStoreFiles()) {
this.compactSplitThread.compactionRequested(region,
- "Region has references on open");
+ region.hasReferences() ? "Region has references on open" :
+ "Region has too many store files");
{code}
> If HBase starts/stops often in less than 24 hours, you end up with lots of
> store files

> Since we don't compact on open and close of regions, all regions that have
> edits will do a flush when the cluster is stopped so that if you do it a
> couple of times in a row it's easy to get more than 10 store files and it
> won't be compacted until the next day. On open, we should check that number
> and compact if needed.
