Karthik Kambatla commented on HADOOP-8891:
------------------------------------------
I am a little confused with {{HttpFSFileSystem}}. {{#initialize()}} doesn't
check for an existing delegation token, nor does it sign up for token renewal.
However, it still implements {{getDelegationToken()}} and
{{setDelegationToken()}}, I am not sure where these methods are actually
invoked from.
Will investigate this further. Meanwhile, I have uploaded a patch that removes
{{DelegationTokenRenewer}} and updates {{WebHdfsFileSystem}} and
{{HftpFileSystem}} accordingly. It would really help if someone could take a
look at the available patch and any thoughts on how to proceed with
{{HttpFSFileSystem}}.
Thanks
Karthik
