Subject [jira] [Updated] (HDFS-2416) distcp with a webhdfs uri on a secure cluster fails
Date Fri, 21 Oct 2011 19:18:33 GMT

     [ https://issues.apache.org/jira/browse/HDFS-2416?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jitendra Nath Pandey updated HDFS-2416:
---------------------------------------

    Attachment: HDFS-2416-branch-0.20-security.patch

The problem happened because tasks connecting to the namenode fail in the absence of kerberos
authentication. The fix is not to require kerberos authentication if token is present and
instead authenticate the token.
 The patch fixes it by bypassing kerberos authentication in AuthFilter in hdfs if token is
there and verifies the token in JspHelper. The same code path is used for token authentication
in hftp also.
