Yiqun Lin updated HDFS-10821: ----------------------------- Description: 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 e05ade8e-fb28-42cf-9aa9-43e564c0ec99,38714337-84fb-4e35-9ea3-0bb47d6da700 {code} was: 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.).
