> Datanode uses a temporary working directory for copying/replicating containers, the default location of this directory is read from system property {{java.io.tmpdir}}. Since all the datanodes are running in same machine/jvm in MiniOzoneCluster we might corrupt the data while the datanodes are moving containers as all the datanodes will be using the same working directory.
> While configuring datanode for MiniOzoneCluster, we should set custom value for {{hdds.datanode.replication.work.dir}} in each datanode instance.
