[jira] [Commented] (HDFS-17017) Fix the issue of arguments number limit in report command in DFSAdmin.

["Viraj Jasani (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HDFS-17017?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17724101#comment-17724101 ] 

Viraj Jasani commented on HDFS-17017:
-------------------------------------

Functionally this change makes sense because all of them are arguments, however in practice "-slownodes" is mostly only meant to be used with "-live". We anyways don't have "slow" and "dead or decommissioned or inmaintenance" nodes.

Thanks for the attempting to fix the max argument [~haiyang Hu]!
