> {{TestNameNodeMXBean#testNameNodeMXBeanInfo}} expects a none-zero nonDFS
> size. The nonDFS size is defined as:
> {quote}
> The space that is not used by HDFS. For instance, once you format a new disk
> to ext4, certain space is used for "lost-and-found" directory and ext4
> metadata.
> {quote}
> It will be possible to fully allocate all spaces in a filesystem for DFS use.
> In which case the nonDFS size will be zero. We can relax the check in the
> test to account for this case.
