Description

The ability to load udfs via "add jar" when the jar is in hdfs was added in ~~HIVE-1157~~. Unfortunately, if the jar's manifest.mf file has a Class-Path attribute referencing jars in the same directory, these jars are not copied from hdsf to the local file system.

It would be great if, after copying the specified jar from hdfs, that jar's manifest was inspected for a Class-Path attribute, and if any mentioned jars were recursively copied in the same fashion.

If this is seen as a desirable feature, I'd be happy to contribute a patch.
