Kan Zhang commented on HADOOP-6419:
-----------------------------------

The last patch also supports Kerberos authentication through the same SASL API.

> 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.
