[jira] [Commented] (HIVE-11089) Hive Streaming: connection fails when using a proxy user UGI

["Wei Zheng (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-11089?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15334922#comment-15334922 ] 

Wei Zheng commented on HIVE-11089:
----------------------------------

Had discussion with [~roshan_naik]. Looks like we didn't have proxy support for Hive streaming from day 1. As Roshan pointed out earlier, the "proxyuser" param was in a private method and was always null. The plan was to support proxy and that didn't happen (so the wiki was also updated).

If proxying is needed, this will be a new feature request. So I will close this ticket as invalid.

> HIVE-7508 "Add Kerberos Support" seems to also remove the ability to specify a proxy user.
> HIVE-8427 adds a call to ugi.hasKerberosCredentials() to check whether the connection is supposed to be a secure connection.
> This however breaks support for Proxy Users as a proxy user UGI will always return false to hasKerberosCredentials().
> See lines 273, 274 of HiveEndPoint.java
> {code}
> this.secureMode = ugi==null ? false : ugi.hasKerberosCredentials();
> this.msClient = getMetaStoreClient(endPoint, conf, secureMode);
> {code}
> It also seems that between 13.1 and 0.14 the newConnection() method that includes a proxy user has been removed.
