Devaraj Das updated HADOOP-6520:
--------------------------------
Attachment: h-6520.patch
Attaching a patch for common. For the mapreduce part, we need to have a
separate jira. This patch disables kerberos login when the env var is set. In
the method getLoginUser in UserGroupInformation, the token file is read and
tokens are loaded.
Thoughts?
> UGI should load tokens from the environment

> 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.
