> Switch from pread to stream should happen under HStore's reentrant lock

> Key: HBASE-18221
> URL: https://issues.apache.org/jira/browse/HBASE-18221
> Project: HBase
> Issue Type: Sub-task
> Components: Scanners
> Affects Versions: 2.0.0, 3.0.0, 2.0.0-alpha-1
> Reporter: ramkrishna.s.vasudevan
> Assignee: ramkrishna.s.vasudevan
> Fix For: 2.0.0, 3.0.0, 2.0.0-alpha-2

>
>
> Found this while debugging HBASE-18186. When we try to reopen the scanners on
> the storefiles while trying to switch over from pread to stream, we do not
> use the HStore's reentrant lock to get the current Storefiles from the
> StoreFileManager. All the scan APIs are guarded under that and we must do it
> here also other wise the CompactedHfileDischarger may cause race issues with
> the HStore's datastructures like here
> {code}
