Ryan Blue commented on CRUNCH-512:
----------------------------------
Yes, all of the jars I'm adding to the distributed cache go through the
DistCache methods, and the jars are [located by
class|https://github.com/kite-sdk/kite/blob/master/kite-tools-parent/kite-tools/src/main/java/org/kitesdk/tools/TaskUtil.java#L137].
> Distributed cache cannot find jar files when using LocalJobRunner.

> I have a Crunch-based task that uses the LocalJobRunner when it is copying
> data to or from HDFS. When HDFS is the default FS and I'm using
> LocalJobRunner, I get a FileNotFoundException in the distributed cache code
> with a strange looking URI:
