      Description

          --bandwidth <arg>             Maximum disk bandwidth to be consumed by
                                        diskBalancer. e.g. 10
          --maxerror <arg>              Describes how many errors can be
                                        tolerated while copying between a pair
                                        of disks.
          --out <arg>                   File to write output to, if not
                                        specified defaults will be used.
          --plan <arg>                  creates a plan for datanode.
          --thresholdPercentage <arg>   Percentage skew that wetolerate before
                                        diskbalancer starts working e.g. 10
          --v                           Print out the summary of the plan on
                                        console
      

      We should

      • Put the unit into --bandwidth, or its help message. Is it an integer or float / double number? Not clear in CLI message.
      • Give more details about --plan. It is not clear what the <arg> is for.
      • --thresholdPercentage, has typo wetolerate in the error message. Also it needs to indicated that it is the difference between space utilization between two disks / volumes. Is it an integer or float / double number?

      Thanks.
