Subject [jira] [Commented] (HIVE-19781) Fix qtest isolation problems
Date Mon, 04 Jun 2018 13:15:00 GMT

Zoltan Haindrich commented on HIVE-19781:
-----------------------------------------

I think the following is happening there is 50-50 chance of using 45 or 46 for the MERGEJOIN
operator; and somehow when explain runs it may get the other one...

> 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
