Major Description
Currently hdds.datanode.dir property is missing. So, datanode data dir is pointing to location /tmp/<<dir>>/hdds.
Some times with this approach we can face issues, as this points to default mount point from docker. On my local setup, because of this I am facing issue like create container is failing with DISK full.
This also helps in knowing where the datanode dir location, instead of guesswork /remembering default dfs.datanode.dir.
