Subject [jira] [Commented] (HIVE-6486) Support secure Subject.doAs() in HiveServer2 JDBC client.
Date Mon, 10 Mar 2014 07:17:50 GMT


Lefty Leverenz commented on HIVE-6486:

[~shivshi], the release note looks good to me.  I'll make a few minor edits when I put it
in the JDBC section of the HS2 Clients wiki (which will probably happen tomorrow), then you
can review to make sure your meaning didn't get changed.

> 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.
