Andrew Purtell resolved HBASE-2634.
-----------------------------------

    Resolution: Not a Problem

> Clean up and document locks in HRegion
> --------------------------------------
>
>                 Key: HBASE-2634
>                 URL: https://issues.apache.org/jira/browse/HBASE-2634
>             Project: HBase
>          Issue Type: Improvement
>          Components: regionserver
>            Reporter: Todd Lipcon
>
> HRegion now has four different lock objects:
> - splitsAndClosesLock (RWLock)
> - newScannerLock (RWLock)
> - updatesLock (RWLock)
> - splitLock (Object)
> It's not well documented what the purpose of each is, and I imagine we may be able to
get rid of at least one.
