[jira] [Commented] (IMPALA-8640) ImpalaTestSuite::create_impala_client() user session is sticky

["Tim Armstrong (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IMPALA-8640?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16858797#comment-16858797 ] 

Tim Armstrong commented on IMPALA-8640:
---------------------------------------

This is a result of the behaviour of the beeswax interface in an insecure mode - if running without security, no username is provided on the initial connection. However you can provide a username with the query(), and the first username provided sticks. HS2 behaves differently and more rationally.

I think this feature of beeswax is pretty broken, so I don't think we should really invest much effort in this. We eventually want to switch to HS2 and HS2 doesn't let you change user per query afaik, it's per-session, so the above APIs that let you change user per query in tests don't really make sense at all.

> {noformat}
> client = self.create_impala_client()
> result = self.execute_query_expect_failure(client, statement, user="foo") --> the client will be bound to user "foo"
> result = self.execute_query_expect_failure(client, statement, user="bar") --> the client will still be bound to user "foo" even though we specify user="bar"
> {noformat}
