Siddharth Seth reopened HDFS-2257:
----------------------------------
{{getDelegationToken}} was deprecated in favor of {{getDelegationTokens}} -
likely along with the introduction of ViewFileSystem.
Hftp does not have an implementation of getDelegationTokens. ViewFs cannot
implement getDelegationToken.
The TokenCache in MapReduce currently ends up making one call to
getDelegationToken and another to getDelegationTokens - likely causing
unnecessary token caching on the Namenode?
> HftpFileSystem should implement getDelegationTokens
