Daryn Sharp commented on HDFS-2385:
-----------------------------------
Sorry I'm late to comment, but I'm confused by the webhdfs renew and cancel.
{code}
final String uri = WebHdfsFileSystem.SCHEME + "://"
+ conf.get("dfs.http.address");
...
return (WebHdfsFileSystem)FileSystem.get(new URI(uri), conf);
{code}
Does this work if webhdfs isn't being used to contact the default namenode? It
would appear that tokens will fail to renew during a distcp from a remote
namenode because the tokens are renewed against the local namenode. Why isn't
the service in the token being used?
