Subject [jira] [Commented] (HIVE-17429) Hive JDBC doesn't return rows when querying Impala
Date Fri, 06 Apr 2018 22:24:00 GMT

    [ https://issues.apache.org/jira/browse/HIVE-17429?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16429084#comment-16429084

Mark Smith commented on HIVE-17429:
-----------------------------------

Hey [~aihuaxu], just a heads-up that while this fix is in the 2.1.x branch and master, it's
not in the 2.2.x or 2.3.x branches.  Since 2.3.x is the latest release available on maven
central just now, it'll probably bite quite a few people trying to use it with Impala.

I've added the relevant releases to the 'Affects Versions' field, but you may want to consider
porting the fix to 2.3 if you're planning to do any more releases before 3.0, since it's
not really usable with Impala without it.

> The Hive JDBC driver used to return a result set when querying Impala.  Now, instead,
it gets data back but interprets the data as query logs instead of a resultSet.  This causes
many issues (we see complaints about beeline as well as test failures).
> This appears to be a regression introduced with asynchronous operation against Hive.
> Ideally, we could make both behaviors work.  I have a simple patch that should fix the
problem.
