Subject [jira] Commented: (HIVE-524) ExecDriver adds 0 byte file to input paths
Date Fri, 29 May 2009 23:43:59 GMT

Zheng Shao commented on HIVE-524:
---------------------------------

Namit, is it convenient to split the patch for this one? That map-side join is a big patch
but this one seems a really small fix.

> 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).
