John Sichi commented on HIVE-1644:
----------------------------------
Oh, I see...the reason it didn't work for you is that your setInputAttributes
method is working on the job object. For MapRedTask, it needs to work on the
conf object instead. So make it take an input parameter and pass in job from
ExecDriver, and conf from MapRedTask.
Since the splits exception happens for both manual/auto, we don't need to try
to address it as part of this JIRA, so you can open a followup for that. But
it means you won't be able to check in a meaningful test case, so better if you
have a fix. When newInputPaths.toString() == "", you could try calling
FileInputFormat.setInputPaths(job, new Path[0]). I'm not sure whether that
will work.

> HIVE-1226 provides utilities for analyzing filters which have been pushed
> down to a table scan. The next step is to use these for selecting available
> indexes and generating access plans for those indexes.
