> Key: HDDS-440

> Project: Hadoop Distributed Data Store
> Issue Type: Bug
> Components: Ozone Datanode
> Reporter: Arpit Agarwal

> Datanode starts but runs in a tight loop forever if it cannot create the DataNode ID directory e.g. due to permissions issues. I encountered this by having a typo in my ozone-site.xml for {{ozone.scm.datanode.id}}.
> In just a few minutes the DataNode had generated over 20GB of log+out files with the following exception:
