> If the HDFS file system is empty then repository configurator gives confusing
> message
> -------------------------------------------------------------------------------------

> Key: RANGER-149
> URL: https://issues.apache.org/jira/browse/RANGER-149
> Project: Ranger
> Issue Type: Bug
> Affects Versions: 0.4.0
> Reporter: Alok Lal
> Assignee: Ramesh Mani
> Priority: Trivial
>
> test of correct hdfs repo relies on non-null file listing. If one tries to
> configure an empty repository then one gets the following message:
> {code}
> Connection Failed.
> Unable to retrieve any files using given parameters, You can still save the
> repository and start creating policies, but you would not be able to use
> autocomplete for resource names. Check xa_portal.log for more info.
> Unable to retrieve any files using given parameters, You can still save the
> repository and start creating policies, but you would not be able to use
> autocomplete for resource names. Check xa_portal.log for more info.
> {code}
> The message is factually correct. It would be helpful if it said something
> to the effect: unable to retrieve any files. Either the file system is
> currently empty or connection wasn't successful.
> While it asks one to look at xa_portal.log in this case the log does not have
> any helpful information because connection in fact was successful.
> h4. Steps to reproduce
> - format the namenode: {{bin/hdfs namenode -format}}
> - confirm that fs is empty {{bin/hdfs dfs -ls -R /}}
> - go to admin portal and test the connection. You will get the above error.
> Check in the xa_portal.log to confirm that there wasn't any connection error
> or exceptions.
> - Now go an create a single file {{bin/hdfs dfs -touchz /test}}
> - go back to admin portal and test the connection. Test would succeed this
> time.
