Nicolas Liochon updated HBASE-10605:
------------------------------------
Assignee: (was: Nicolas Liochon)
> Manage the call timeout in the server
> -------------------------------------
>
> Key: HBASE-10605
> URL: https://issues.apache.org/jira/browse/HBASE-10605
> Project: HBase
> Issue Type: Improvement
> Components: IPC/RPC, regionserver
> Affects Versions: 0.99.0
> Reporter: Nicolas Liochon
>
> Since HBASE-10566, we have an explicit call timeout available in the client.
> We could forward it to the server, and use this information for:
> - if the call is still in the queue, just cancel it
> - if the call is under execution, makes this information available in
> RpcCallContext (actually change the RpcCallContext#disconnectSince to
> something more generic), so it can be used by the query under execution to
> stop its execution
> - in the future, interrupt it to manage the case 'stuck on a dead datanode'
> or something similar
> - if the operation has finished, don't send the reply to the client, as by
> definition the client is not interested anymore.
> From this, it will be easy to manage the cancellation:
> disconnect/timeout/cancellation are similar from a service execution PoV
