-----------------------------------
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.
