> HIVE-5155 addresses the problem of kerberos authentication in multi-user middleware server
using proxy user.  In this mode the principal used by the middle ware server has privileges
to impersonate selected users in Hive/Hadoop. 
> This enhancement is to support Subject.doAs() authentication in  Hive JDBC layer so that
the end users Kerberos Subject is passed through in the middle ware server. With this improvement
there won't be any additional setup in the server to grant proxy privileges to some users
and there won't be need to specify a proxy user in the JDBC client. This version should also
be more secure since it won't require principals with the privileges to impersonate other
users in Hive/Hadoop setup.
