Subject [jira] [Commented] (HDFS-3113) httpfs does not support delegation tokens
Date Mon, 02 Jul 2012 18:23:22 GMT

    [ https://issues.apache.org/jira/browse/HDFS-3113?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13405203#comment-13405203

Alejandro Abdelnur commented on HDFS-3113:
------------------------------------------

bq. Would you please elaborate ...

If a client uses webhdfs:// they'll be using WebHdfsFileSystem class, the HttpFSFileSystem
class is not avail for clients. WebHDFSFileSystem usas the token renewer, and that one will
kick in. The WebHdfsFileSystem client will get a token from HttpFS server and will renew it
against HttpFS. It is not the intention for a token from WebHdfs server to be used against
HttpFS server or viceversa. Does this address your concern?

I'll look at the Token#decoderIndentifier, thx
