> TokenCache does not cache viewfs credentials correctly

> URL: https://issues.apache.org/jira/browse/MAPREDUCE-3529
> Project: Hadoop Map/Reduce
> Issue Type: Bug

> viewfs returns a list of delegation tokens for the actual namenodes.
> TokenCache caches these based on the actual service name - subsequent calls
> to TokenCache end up trying to get a new set of tokens.
> Tasks which happen to access TokenCache fail when using viewfs - since they
> end up trying to get a new set of tokens even though the tokens are already
> available.
> {noformat}
> Error: java.io.IOException: Delegation Token can be issued only with kerberos
