Joydeep Sen Sarma commented on HIVE-1454:
-----------------------------------------
it's difficult to add queries that can test this. the reason is that we need
two different valid and different Hadoop FileSystems to replicate this problem.
this is not trivial.
medium term - as part of HIVE-1408 - i will add a new dummy Hadoop filesystem
(that will just use local storage underneath). Then we will be able to
systematically test this using our regression queries.

> this is because of the changes in HIVE-543. We switched to using local
> storage for intermediate data for local mode queries. However there are code
> paths that are incorrectly allocating intermediate storage where they should
> be allocating external file system storage (based on table/directory uri).
> This is causing regressions in running queries in local mode.
