Haohui Mai commented on HDFS-6407:
----------------------------------

Thanks for working on this.

My understanding is that only the datanode tab needs to be sorted and 
paginated, thus it should not affect other tables. Therefore I'm leaning 
towards a simpler solution instead of introducing a plugin. Let me experiment a 
little bit.

> 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.
