> When a drive fails and it is unmounted for service, if the data node process is stopped/started using Ambari the dfs.data.dir path that was housed on that drive is re-created, but this time on the / partition leading to out of disk space issues and data being created on the wrong volume.
> In this case we only want the Ambari Agent to create dfs.data.dir's during installation, and not after as this makes drive replacements difficult.
