Description

The submitJob RPC finally creates a timer task for renewing the delegation tokens of the submitting user. This timer task inherits the context of the RPC handler that runs in the context of the job submitting user, and when it tries to create a filesystem, the RPC client tries to use the user's credentials. This should instead use the JobTracker's credentials.
