Benoy Antony commented on HDFS-6407:
------------------------------------
#1 can be fixed pretty easily by applying special logic for the columns which
needs custom sorting.
#2 is not a plugin specific issue as the major delay is for client-server
communication. Since sorting and regeneration happens at the client side, it
should be quick. This can be easily tested.
A standard solution for sorting is better than a custom solution for many
reasons including maintainability, usability and free enhancements.
Pagination can be done independently of sorting.

> 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.
