-----------------------------------

             Summary: FS-CS converter tool: issue warning on dynamic auto-create mapping rules
                 Key: YARN-10135
                 URL: https://issues.apache.org/jira/browse/YARN-10135
             Project: Hadoop YARN
          Issue Type: Sub-task
            Reporter: Peter Bacsko
            Assignee: Peter Bacsko


The converter tool should issue a warning whenever the conversion results in mapping rules
similar to these:

{{u:%user:[managedParentQueueName].[queueName]}}

{{u:%user:[managedParentQueueName].%user}}

{{u:%user:[managedParentQueueName].%primary_group}}

{{u:%user:[managedParentQueueName].%secondary_group}}

{{u:%user:%primary_group.%user}}

{{u:%user:%secondary_group.%user}}

{{u:%user:[managedParentQueuePath].%user}}

 

The reason is that right now it's fully clear how we'll handle a case like "u:%user:%primary_group.%user",
where "%primary_group.%user" might result in something like "users.john". 

In case of "u:%user:[managedParentQueuePath].%user" , the [managedParentQueuePath] is a result
of a full path from Fair Scheduler. Therefore it's not going to be a leaf queue. 

The user might be required to do some fine tuning and adjust the property "auto-create-child-queues".
We should display a warning about these additional steps.
