    [ https://issues.apache.org/jira/browse/HIVE-6486?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13909225#comment-13909225 ] 

Shivaraju Gowda commented on HIVE-6486:
---------------------------------------

Other than the use case in the Description of this issue, the attached patch will also enhance Kerberos support in Hive JDBC driver by allowing the user to programmatically login to the kerberos(i.e without a key tab or ticket cache, etc.). Furthermore this is done without the dependency on the other component's jars(hadoop-core*.jar).

> 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.
