Subject [jira] [Commented] (SQOOP-3018) Hadoop MapReduce job submission be done in client user UGI?
Date Fri, 14 Oct 2016 17:11:20 GMT

    [ https://issues.apache.org/jira/browse/SQOOP-3018?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15575894#comment-15575894
] 

Yan braun commented on SQOOP-3018:
----------------------------------

Our biggest concern is that when a job is run on the grid with root user privilege, it has
full access to local file system, and it can run user code (such as through submitting custom
jars).

But MapReduce job submission is done using Sqoop user UGI, which makes all jobs from different
users run in Sqoop user's hadoop queue  instead of client users' own queue.   
> This is a follow-up JIRA after our discussions with Abraham Fine on whether this will
be on sqoop2 road map in the near future.  Thanks.
