Zheng Shao commented on HIVE-204:
---------------------------------
+1 but it failed some 0.17.0 tests.
Seems like class path problem.

For this patch, we need to do both:
{code}
ant clean test
ant -Dhadoop.version=0.17.0 clean test
{code}
If the tests are passed, I am OK with this committed. But I am gone for the
next 2 weeks, so maybe somebody else can help commit it.
> Provide option to run hadoop via TestMiniMR

> Key: HIVE-204
> URL: https://issues.apache.org/jira/browse/HIVE-204
> Project: Hadoop Hive
> Issue Type: Improvement
> Components: Testing Infrastructure
> Reporter: Raghotham Murthy
> Assignee: Namit Jain
> Attachments: hive.204.1.patch, hive.204.2.patch, hive.204.3.patch

>
> Right now MapRedTask does an exec on the hadoop command line. This prevents
> us from stepping through query execution code. If there were an option to run
> hadoop via MiniMR, this will create tasks within the same VM and so allows
> stepping into the execution code. See,
> src/test/org/apache/hadoop/mapred/TestMiniMRWithDFS.java in the hadoop source
> code for an example.
