Daryn Sharp commented on HDFS-4010:
-----------------------------------
{{setDelegationToken}} should also be removed since it's only there for the
defunct renewer to fetch and set a new token when renewal fails. This never
worked anyway outside the context of a client with a TGT. Otherwise it looks
good!
> Remove unused TokenRenewer implementation from WebHdfsFileSystem and
> HftpFileSystem
