> 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
> Priority: Major
> Labels: fs2cs
> Attachments: YARN-10135-001.patch, YARN-10135-002.patch

>
> 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.
