Subject [jira] [Created] (HDFS-11358) DiskBalancer: Report command supports reading nodes from host file

Yiqun Lin created HDFS-11358:
--------------------------------

             Summary: DiskBalancer: Report command supports reading nodes from host file
                 Key: HDFS-11358
                 URL: https://issues.apache.org/jira/browse/HDFS-11358
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: diskbalancer
    Affects Versions: 3.0.0-alpha2
            Reporter: Yiqun Lin
            Assignee: Yiqun Lin


This is a improvement of JIRA HDFS-10821. In HDFS-10821, it supports the {{diskbalancer report}}
command can be executed with multiple nodes. But the multiple nodes are read from a nodes
string. It will be not good to use when the cluster is big enough. A better way we can do
is making that can be read from a host file as that has been done in many places in HDFS(ex.
 decommission, balancer). This JIRA focus on this point, and will makes this done in diskbalancer.
