Subject [jira] Commented: (HIVE-524) ExecDriver adds 0 byte file to input paths
Date Sat, 30 May 2009 01:17:07 GMT

Joydeep Sen Sarma commented on HIVE-524:
----------------------------------------

maybe we should get rid of the assumption that the subqueries need to produce output directories?

> In the addInputPaths method in ExecDriver:
> If the input path of a partition cannot be found or contains no files with data in them,
a 0 byte file is created and added to the job instead. This causes our custom InputFormat
to throw an exception since it is asked to process an unknown file format (not an lzo file).
