Daryn Sharp updated MAPREDUCE-5199:
-----------------------------------
Attachment: MAPREDUCE-5199.patch
* child job is guaranteed to not acquire the parent job's app token
* AM uses full complement of tokens from the container launch context passed
via the UGI.
* AM strips out the app token from the credentials of tasks
Patch appears to work with preliminary testing. Later today will report
results of testing with oozie on a secure cluster.
> AppTokens file can/should be removed
