Subject [jira] [Commented] (HDFS-6407) new namenode UI, lost ability to sort columns in datanode tab
Date Wed, 22 Jul 2015 17:12:04 GMT

    [ https://issues.apache.org/jira/browse/HDFS-6407?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14637207#comment-14637207

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.

> 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.
