Subject [jira] [Commented] (HDFS-6407) new namenode UI, lost ability to sort columns in datanode tab
Date Wed, 22 Jul 2015 21:14:05 GMT

    [ https://issues.apache.org/jira/browse/HDFS-6407?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14637638#comment-14637638

Haohui Mai commented on HDFS-6407:

-    <td>{capacity|fmt_bytes}</td>
-    <td>{used|fmt_bytes}</td>
-    <td>{nonDfsUsedSpace|fmt_bytes}</td>
-    <td>{remaining|fmt_bytes}</td>
+    <td>{capacity}</td>
+    <td>{used}</td>
+    <td>{nonDfsUsedSpace}</td>
+    <td>{remaining}</td>
-    <td>{blockPoolUsed|fmt_bytes} ({blockPoolUsedPercent|fmt_percentage})</td>
+    <td>{blockPoolUsed} ({blockPoolUsedPercent|fmt_percentage})</td>

This change is unacceptable as it will hinder readability as the numbers can be as large as
couple terabytes.

bq. Also loing the ability to sort in 2.7 and lost legacy UI is preventing my company from
using 2.7

Also can you elaborate why losing the legacy UI prevent you to use 2.7?

Patches are definitely welcome but as I pointed out in the previous comments it is the wrong
direction to put sorting abilities using datatables. Approaches that really separate the controls
and the views are definitely the way to go.

> 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.
