Subject [jira] [Created] (RANGER-861) Ranger does not execute jobs under original user
Date Wed, 24 Feb 2016 12:55:18 GMT
Bolke de Bruin created RANGER-861:

             Summary: Ranger does not execute jobs under original user
                 Key: RANGER-861
                 URL: https://issues.apache.org/jira/browse/RANGER-861
             Project: Ranger
          Issue Type: Improvement
    Affects Versions: 0.5.2, 0.6.0
            Reporter: Bolke de Bruin

When using Ranger hive queries are executed under a superuser account instead of the users'
own account . This means that in the UIs one is unable to distinguish who is running what
job because they all reside under the same user. This is a usability issue.

Also "What this means is that Hiveserver2 will run MR jobs in HDFS as the original user" mentioned
in http://hortonworks.com/blog/best-practices-for-hive-authorization-using-apache-ranger-in-hdp-2-2/
does not seem to be the case. The screenshots also support this as the files are being owned
by the hive user and permissions are only set for the hive user.

For HDFS access can be granted by Ranger. It (ranger) however expects the files to be owned
by the 'hive' user otherwise they won't be accessible by services that integrate with ranger,
although the proper permissions/acls are in place.

Moreover, logging for the different services now also doesn't include the user ids anymore
making it easier for someone to manipulate the logs. We consider this a security issue.

We would like to see the option of:

1. Execution of (hive etc) jobs under the original user id
2. Making sure Ranger's hdfs policies are complementary to HDFS permissions (or setting the
right permissions on HDFS?), again making sure access is done under the original account,
not requiring file ownership by the hive user.
