Kam Kasravi reopened YARN-885:
------------------------------
This actually occurs on trunk and branch-2 and is the result of recent RPC
changes due to Kyle Leckie when working on HADOOP-9621. The fix supplied by
Vinod and Daryn was to not switch to simple if other auth methods were
available such as tokens supplied by a secrets manager. However this still
results in unit test failures and requires a patch I had made which sets
IPC_CLIENT_FALLBACK_TO_SIMPLE_AUTH_ALLOWED_KEY in the ContainerLocalizer
constructor and adds the creds tokens to the local context in
ContainerLocalizer.runLocalization just like they're added to the user context
in the same method. I'll upload the patch later today.
