Hello,

Thank you for the responses.
I get the point that it is not possible to load a pig script file from
local file system from within a oozie workflow, not even while using the
Hue - oozie interface.

Is it possible to load a pig script stored on S3 into a workflow, if the
cluster is an EC2 cluster. running CDH4.

Can i specify the pig script file in the normal way as I would refer to any
normal file on S3 from within hdfs?

Thank you for the help,

Regards,
