> Currently , diskBalancer report command "top" option takes values like "AAA" as well negative/decimal values and gives output. These invalid values should not be processed and some error/warning should be given.
> For Example,
> $ hdfs diskbalancer -report -top -100
> 17/12/19 15:07:01 INFO command.Command: Processing report command
> 17/12/19 15:07:02 INFO balancer.KeyManager: Block token params received from NN: update interval=10hrs, 0sec, token lifetime=10hrs, 0sec
> 17/12/19 15:07:02 INFO block.BlockTokenSecretManager: Setting block keys
> 17/12/19 15:07:02 INFO balancer.KeyManager: Update block keys every 2hrs, 30mins, 0sec
> 17/12/19 15:07:02 INFO command.Command: Reporting top -100 DataNode(s) benefiting from running DiskBalancer.
