> For MapReduce tasks, we need not only the task itself, but child processes to
> get the delegation tokens, therefore we need an environment variable that if
> set loads a token cache into the login UGI. The task tracker can set this
> property so that tasks (and child processes of the tasks, such as streaming
> and pipes) have the job's tokens automatically.
