Namit Jain commented on HIVE-3341:
----------------------------------
I tried to run some tests for hadoop 23: by following steps above::
ant clean && ant very-clean && ant package
ant test -Dhadoop.mr.rev=23 -Dtest.print.classpath=true
-Dhadoop.version=2.0.0-alpha -Dhadoop.security.version=2.0.0-alpha
I got the following error::
compile-test:

Can you put the exact instructions of how to run a particular test 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.
