Namit Jain commented on HIVE-204:
---------------------------------
1. You need reflection, since you cant cast dfs to a given class (it is
different in 17 and 19) - without casting appropriately, you cannot call the
method
2. Will do
3. By default, qfile gets all the .1 files in the test directory, and I did not
want to change that behavior. I did not want to run miniMR cluster tests for
all the files,
since it takes a awefully long time. Once the tests have been parallelized,
I agree clusterQueryFiles can be removed, but we would need it till then.
Will do 2, and upload the new patch
> Provide option to run hadoop via TestMiniMR

> 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.
