[jira] [Commented] (APEXCORE-736) Security fix : YarnClient in StreamingContainerManager

    [ https://issues.apache.org/jira/browse/APEXCORE-736?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16035997#comment-16035997 ] 

Pramod Immaneni commented on APEXCORE-736:
------------------------------------------

The exception is thrown because yarn web services would expect the client to authenticate with kerberos credentials and the client, in this case the container, has none.

> Currently we are using a WebServicesClient in StreamingContainerManager to get container report from Yarn.
> Using the WebServicesClient will throw and exception if the webservices are kerberized.
> We should use a YARN client instead which can access kerberized YARN webservices as per its access levels.
