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.
> distcp with a webhdfs uri on a secure cluster fails
