Andrew Purtell resolved HBASE-2751.
-----------------------------------
Resolution: Won't Fix
Stale issue. Reopen if still relevant (if there's new activity)
> Consider closing StoreFiles sometimes
> -------------------------------------

> Key: HBASE-2751
> URL: https://issues.apache.org/jira/browse/HBASE-2751
> Project: HBase
> Issue Type: Improvement
> Reporter: Jean-Daniel Cryans
> Priority: Minor
>
> Having a lot of regions per region server could be considered harmless if
> most of them aren't used, but that's not really true at the moment. We keep
> all files opened all the time (except for rolled HLogs). I'm thinking of 2
> solutions
> # Lazy open the store files, or at least close them down after we read the
> file info. Or we could do this for every file except the most recent one.
> # Close files when they're not in use. We need some heuristic to determine
> when is the best moment to declare that a file can be closed.
> Both solutions go hand in hand, and I think it would be a huge gain in order
> to lower the ulimit and xceivers-related issues.
