[jira] [Commented] (HIVE-19781) Fix qtest isolation problems

["Zoltan Haindrich (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-19781?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16500130#comment-16500130 ] 

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

> 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
