[jira] [Commented] (HBASE-21478) Make table sorted when displaying rsgroup info in shell and master web UI

["Xiang Li (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-21478?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16686494#comment-16686494 ] 

Xiang Li commented on HBASE-21478:
----------------------------------

I do not plan to change the logic of TableName#compareTo(), because RSGroupInfo#getTables() has a lot of usage. As an alternative, I only plan to update the output when displayed: May I provide a new function called RSGroupInfo#getTablesSortedByNamespaceAndName() and use the new function in hbase shell and master web UI when the tables are displayed?

> Regarding the output of the command of "get_rsgoup" in hbase shell, or the section of "Server Group" of HMaster's web UI, the tables are not sorted, so not quite easy to read, like:
> {code}
> hbase(main):003:0> get_rsgroup 'default'
> GROUP INFORMATION
> ...
> Tables:
> table3
> ns2:table22
> table1
> ns1:table11
> ...
> {code}
> They could be sorted in the order of namespace then table name:
> {code}
> table1
> table3
> ns1:table11
> ns2:table22
> {code}
