Sushanth Sowmyan commented on HIVE-3341:
----------------------------------------
Namit, the issue you face is the issue reported in
https://issues.apache.org/jira/browse/HIVE-3156 that I referred to in the
initial bug report. Since we used to earlier have other hadoop jars in the test
compile classpath, that'd succeed, but fail during runtime. With this patch,
the visibility of that problem moved from test runtime to test compiletime 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.
