--------------------------------
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.
