Namit Jain commented on HIVE-204:
---------------------------------
1. I agree with the mode approach instead of another target. But we still need
minimr.query.files to run the tests with the build - which tests get picked up
by default.
So, it is a just a cleaner way - let us talk about it offline
2. conf.set("hive.metastore.warehouse.dir",
fsName.concat("/build/ql/test/data/warehouse/"));
Note that a concatenation is being performed above.
new MiniMRCluster() sets the configuration variable fs.default.name.

> 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.
