Prasad Chakka commented on HIVE-489:
------------------------------------
488 only creates parent directory before moving the data (both insert overwrite
and load) but it doesn't validate the output path before executing the job.Hive
should validate the output path while generating the plan so that job wouldn't
be executed unnecessarily.
> compiler should check for validity of output paths before job submission

> Project: Hadoop Hive
> Issue Type: Bug
> Components: Query Processor
> Reporter: Joydeep Sen Sarma
>
> couple of hours after a job has run - finding that the move operation failed
> (because the output directory did not exist and move doesn't make parent
> directories automatically). No Trash - output is gone. Hive should have
> barfed on this in the compile phase.
