Jakob Homan commented on HADOOP-6419:
-------------------------------------

The patches were submitted in relatively rapid exception, but with the expectation that new jars would be submitted in time for dependencies to be fixed.  It's a temporary problem until the new jars are generated by Hudson.  Once the new jar is available for the build, the method is available and all is well.

> 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.
