Daryn Sharp updated HADOOP-8965:
--------------------------------
Attachment: HADOOP-8965.example.patch
Barebones patch to demonstrate possible ipc client changes to force use of
tokens in SIMPLE auth.
In conjunction with HDFS-4056, I'll add another conditional for whether to look
for tokens.
> Allow client to specify internal authentication

> The RPC client currently uses a token if present, else it falls back to
> authentication. This creates an ambiguity in the client if SIMPLE auth is
> allowed to use tokens. A task will continue to run if the task loses its
> tokens because it will fallback to SIMPLE auth - this would be a bug. There
> should be a means to specify that tasks must use tokens to avoid the
> ambiguity.
