Subject [jira] [Commented] (HIVE-5636) Introduce getPartitionColumns() functionality from HCatInputFormat
Date Fri, 14 Feb 2014 23:37:21 GMT

Sushanth Sowmyan commented on HIVE-5636:
----------------------------------------

In my previous patch, I'd removed some of the older deprecated methods, but I've avoided doing
that in this current patch given that it's so late in this release cycle - I think it's better
to approach that after our next release.

> As of HCat 0.5, we made the class InputJobInfo private for hcatalog use only, and we
made it so that setInput would not modify the InputJobInfo being passed in.
> However, if a user of HCatInputFormat wants to get what Partitioning columns or Data
columns exist for the job, they are not able to do so directly from HCatInputFormat and are
forced to use InputJobInfo, which currently does not work. Thus, we need to expose this functionality.
