--------------------------------------------
Summary: Inconsistent listing of queries under webUI/queries page
for HUE submitted queries
Key: IMPALA-6122
URL: https://issues.apache.org/jira/browse/IMPALA-6122
Project: IMPALA
Issue Type: Bug
Components: Backend
Affects Versions: Impala 2.7.0
Reporter: Mala Chikka Kempanna
Attachments: select query enters completed list with exception
state.png, select count query enters completed list with finished state.png,
select count query goes into wait to be closed list.png, select query does not
go into waiting to be closed list.png
On host:25000/queries page , I see different behavior for different queries.
Here for example idle session timeout is set to 2 minutes.
1) Good behavior
a) When I run "select count(*) from sample_08" query, I see that as soon as
query returns result on hue, the query is moved into waiting to be closed state
- file image attached "select count query goes into wait to be closed list.png"
b) And after expiration of idle session time, the query is moved to
completed list with FINISHED state. - File image attached "select count query
enters completed list with finished state.png"
2) Bad behavior
a) When I run "select * from sample_08" query, I see that even after soon
the query returns result, the query continues to stay in "in-flight" listing on
web UI. Image attached "select query does not go into waiting to be closed
list.png".
This is confusing to end users because, query state shows "FINISHED" but query
continues to be listed under "in-flight" listing.
b) This query continues to be listed under "in-flight" list until idle session
expires. This is even ore confusing, because, it is supposed to be listed under
"waiting to be closed" list when session goes idle.
c) And after expiration of idle session time, this query is moved to completed
list with EXCEPTION state.
The query status and listing on WEB UI should be uniform for all types of
queries. This needs to be fixed.
