    [ https://issues.apache.org/jira/browse/KYLIN-2683?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16092777#comment-16092777 ] 

liyang commented on KYLIN-2683:
-------------------------------

In the patch, will {{UserGroupInformation.loginUserFromSubject(null)}} impact the current login user of the whole process? If yes, it may impact other Hadoop operations later.

> When the datasource is kerberized, the behavior of reloading kerberos token is different between "Cube Build" and "Load Hive Table".
> I summarized the detail of this behavior in the attached image.
>  
> I think BeelineHiveClient#init shuold be implementad like following.
