Description

Currently setting a file/archive in the DistributedCache classpath creates a FileSystem instance to fully qualify the path, even if the path given is already fully qualified.

This forces a connection to the cluster.

The methods should check if the path is already fully qualified and if so it should not create a FileSystem instance and try to qualify the path.

This would allow creating a jobconf in disconnected mode until submission time.
