    Description

      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.
