[jira] [Reopened] (HDFS-2257) HftpFileSystem should implement getDelegationTokens

     [ https://issues.apache.org/jira/browse/HDFS-2257?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

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?
