Subject [jira] [Commented] (HIVE-3341) Making hive tests run against different MR versions
Date Tue, 14 Aug 2012 08:41:38 GMT


Namit Jain commented on HIVE-3341:

@carl, @ashutosh, can you update the instructions for running tests on 23 ?
If it does not work, I would have to do -1 on this, and this patch needs to be backed out,
or a 
followup needs to be filed for 23.

> After we build hive, we want to have the ability to run unit tests against specific hadoop
versions. Currently, the classpath constructed has multiple hadoop jars, which makes compiling
okay, but running non-deterministic.
> An example is HIVE-3156, where running against 0.23 shows issues with a couple of tests
(which should either be shimmed out, or separated into directories the way it's done in the
shims/ directory) - It would also be nice to find these issues out at test-compile time itself,
rather than having them fail at test runtime.
