------------------------------------
Summary: Use scan queues/executors for scans, when
RWQueueRpcExecutor used
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
When we use RWQueueRpcExecutor, all scans should be handled by scan handler
threads, not read handler.
https://issues.apache.org/jira/browse/HBASE-17508
Before this patch, 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 the patch, actual scan behavior happened while opening a scanner,
I think this request should probably be executed in scan handlers when using
RWQueueRpcExecutor.
