> Key: HBASE-22715
> URL: https://issues.apache.org/jira/browse/HBASE-22715
> Project: HBase
> Issue Type: Bug
> Affects Versions: 1.4.10
> Reporter: Jeongdae Kim
> Assignee: Jeongdae Kim
> Priority: Minor
> Fix For: 3.0.0, 1.5.0, 2.3.0, 2.2.1, 2.1.6, 1.4.11
>
>
> When we use RWQueueRpcExecutor, all scans should be handled by scan handler
> threads, not read handler.
>
> Before HBASE-17508, when calling openScanner() in client, a region server
> doesn't make results, just open scanner and return scanner id. So, this
> request(open) is executed in read handlers intentionally.
>
> However, since HBASE-17508,, actual scan behavior happened while opening a
> scanner,
> I think this request should probably be executed in scan handlers when using
> RWQueueRpcExecutor.
