> Reviewing HDFS recommendation code for namenode_heapsize,
> namenode_opt_newsize and namenode_opt_maxnewsize, it looks like the
> calculations are not taking into account the number of datanodes and disks
> per datanode.
> HDFS recommendations currently gives the following output
> {code}
> "configurations": {
> "hadoop-env": {
> "properties": {
> "namenode_heapsize": "1024",
