---------------------------------------
The content in the documentation looks good to me. Please feel free to edit it
for grammatical and formatting purposes. The long line in the code snippet can
be broken up as such
String JDBC_DB_URL = "jdbc:hive2://HiveHost:10000/default;" ||
"principal=hive/localhost.localdom...@example.com;" ||
"auth=kerberos;kerberosAuthType=fromSubject";
> 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.
