Haohui Mai commented on HDFS-6407:
----------------------------------
bq. I still use the plugin datatable...
I made it quite explicit why using datatable is a bad idea. Please see
https://issues.apache.org/jira/browse/HDFS-6407?focusedCommentId=14232267&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14232267
The key issue here is that the view does not map directly to the data.The only
reasonable approach to me is to sort internally and to generate the data to
power the views, but not working around and parsing data pretty-formatted data
and sorting them.
> new namenode UI, lost ability to sort columns in datanode tab

> old ui supported clicking on column header to sort on that column. The new ui
> seems to have dropped this very useful feature.
> There are a few tables in the Namenode UI to display datanodes information,
> directory listings and snapshots.
> When there are many items in the tables, it is useful to have ability to sort
> on the different columns.
