Subject [jira] [Commented] (HIVE-19781) Fix qtest isolation problems
Date Mon, 04 Jun 2018 12:09:00 GMT


Zoltan Haindrich commented on HIVE-19781:

after a few hours of painfull debugging...the following seems to be happening:

* explain analyze rowcounts are appearing and disappearing randomly...
* with a high chance also a few operator id-s are changing sometimes...
* the property being set in the other test doesn't matter; I currently has an empty second
qtest....which runs after the EA2

>             Project: Hive
>          Issue Type: Bug
>            Reporter: Zoltan Haindrich
>            Assignee: Zoltan Haindrich
>            Priority: Major
> with HIVE-19237 the following happens:
> * running explainanlayze_2 locally produces different operator ids in the plan than on
the ptest server
> * I've narrowed this down to making a single change to "hive.fetch.task.conversion" in
a different test
> I feel that the isolation is somewhere broken...hiveconf changes may not inflict changes
in different tests
