> Currently 'dfs.datanode.failed.volumes.tolerated' supports number of
> tolerated failed volumes to be mentioned. This configuration change requires
> restart of datanode. Since datanode volumes can be changed dynamically,
> keeping this configuration same for all may not be good idea.
> Support 'dfs.datanode.failed.volumes.tolerated' to accept special
> 'negative value 'x' to tolerate failures of upto "n-x"
