--------------------------------------
After an unconscionable delay, I've put a first draft in the wiki:
* [HiveServer2 Clients -- JDBC Client Setup for a Secure Cluster -- Multi-User
Scenarios and Programmatic Login to Kerberos KDC |
https://cwiki.apache.org/confluence/display/Hive/HiveServer2+Clients#HiveServer2Clients-Multi-UserScenariosandProgrammaticLogintoKerberosKDC]
This is just a start. The heading has obvious flaws. For a while there was a
subheading about middleware, but all of its information got moved into other
sections. Please feel free to revise or suggest revisions, because this could
be organized various other ways and I might have garbled some of the ideas.
Can the long line in the code snippet be broken into multiple lines?
> Support secure Subject.doAs() in HiveServer2 JDBC client.

> 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.
