> DiskBalancer query command currently reports planID (SHA512 hex) only.
> Currently ongoing disk balancing activity in a datanode can be cancelled
> wither by planID + datanode_address or just by pointing to the right plan
> file. Since there could be many plan files, to avoid ambiguity its better if
> query command can report the plan file path also.
> {noformat}
> $ hdfs diskbalancer --help query
> usage: hdfs diskbalancer -query <hostname> [options]
> Query Plan queries a given data node about the current state of disk
> balancer execution.
> --query <arg> Queries the disk balancer status of a given datanode.
> Query command retrievs *the plan ID* and the current running state.

> $ hdfs diskbalancer --help cancel
> *usage: hdfs diskbalancer -cancel <planFile> | -cancel <planID> -node
> <hostname>*
> Cancel command cancels a running disk balancer operation.
> --cancel <arg> Cancels a running plan using a plan file.
> --node <arg> Cancels a running plan using a plan ID and hostName
> Cancel command can be run via pointing to a plan file, or by reading the
> plan ID using the query command and then using planID and hostname.
> Examples of how to run this command are
> hdfs diskbalancer -cancel <planfile>
> hdfs diskbalancer -cancel <planID> -node <hostname>
