Subject [jira] [Commented] (HIVE-6248) HCatReader/Writer should hide Hadoop and Hive classes
Date Fri, 24 Jan 2014 18:45:44 GMT


Ashutosh Chauhan commented on HIVE-6248:

I think we should also create a wiki doc for it to document usage of this api. In case an
overall page for this already exists somewhere, we  need to update it with changes.

> HCat's HCatReader and HCatWriter interfaces expose Hadoop classes Configuration and InputSplit,
as well as HCatInputSplit.  This exposes users to changes over Hadoop or HCatalog versions.
 It also makes it harder to some day move this interface to use WebHCat, which we'd like to
do.  The eventual goal is for this interface to not require any other jars (no Hadoop, Hive,
etc.)  As a first step to this the references to Hadoop and HCat classes in the interface
should be hidden.
