> Since HDFS-10813 has committed to the trunk, then we can use {{getNodes}}
> method to parse the nodes string and support multiple nodes with {{hdfs
> diskbalancer}} subcommands(ex -report, -query). In this JIRA, we are focusing
> on the subcommand {{-report}}.
> That means we can use command {{hdfs diskbalancer -report -node}} to print
> one or one more datanodes report info. A test input command(here I use UUID
> to specify one datanode):
> {code}
> hdfs diskbalancer -report -node
