Need generalized multi-token filesystem support
-----------------------------------------------
Key: MAPREDUCE-3825
URL: https://issues.apache.org/jira/browse/MAPREDUCE-3825
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: security
Affects Versions: 0.23.1, 0.24.0
Reporter: Daryn Sharp
Assignee: Daryn Sharp
This is the counterpart to HADOOP-7967. The token cache currently tries to
assume a filesystem's token service key. The assumption generally worked while
there was a one to one mapping of filesystem to token. With the advent of
multi-token filesystems like viewfs, the token cache will try to use a service
key (ie. for viewfs) that will never exist (because it really gets the mounted
fs tokens).
