-----------------------------------
Resolution: Won't Fix
> GetOperationStatus prevents expiring sessions
> ---------------------------------------------
>
> Key: IMPALA-9169
> URL: https://issues.apache.org/jira/browse/IMPALA-9169
> Project: IMPALA
> Issue Type: Bug
> Components: Infrastructure
> Affects Versions: Impala 2.8.0
> Reporter: Xiaomin Zhang
> Priority: Major
>
> With the fix of IMPALA-4488, GetOperationStatus keeps the session alive so the client can wait for the running query finished before it fetches result. This works perfectly for *DBC clients, but unfortunately leads to issues for HUE.
> Unlike other clients, HUE has a periodical status check for all queries opened in the UI to update the query status. This is hard-coded as 5 minutes, and any sessions opened by HUE won't be expired if the --idle_session_timeout is longer than 5 minutes, hence session expiration is not working properly for HUE.
> I think GetOperationStatus should not reset session's last_accessed timestamp for finished or expired queries.
