-------------------------------------
Summary: 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
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.
