    Description

      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.
