Subject [jira] [Commented] (HIVE-3341) Making hive tests run against different MR versions
Date Tue, 14 Aug 2012 17:22:38 GMT

    [ https://issues.apache.org/jira/browse/HIVE-3341?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13434286#comment-13434286

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.
