Yan braun commented on SQOOP-3018:

[~abrahamfine] and [~jarcec],  Are you saying that a user who doesn't have 
access to a given database can have access to a link object of that database 
and run a sqoop job to load data into that database?  if so, could you give a 
specific use case?

In our case, we would only want a user to be able to access a database through 
sqoop if the user has credentials for the database.   What data the user can 
access in the database depends on the privilege of the credentials provided by 
the user through the link config.

>             Project: Sqoop
>          Issue Type: New Feature
>          Components: connectors/hdfs
>    Affects Versions: 1.99.7
>            Reporter: Yan Braun
> Hdfs Connector read and write to HDFS in client user UGI when proxyUser is 
> enabled.  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.
