Doug Cutting commented on HADOOP-6419:
--------------------------------------

> It would still be good to get reassurance that someone else was looking at the issue, even if the review is just a "+1 patch looks good" 

Yes, that is project policy.  A committer who is not the patch author should provide a +1 comment before a patch is committed.

> The authentication mechanism to use will be SASL DIGEST-MD5 (see RFC-2222 and RFC-2831) or SASL GSSAPI/Kerberos. Since J2SE 5, Sun provides a SASL implementation by default. Both our delegation token and job token can be used as credentials for SASL DIGEST-MD5 authentication.
