Subject [jira] Commented: (HADOOP-470) Some improvements in the DFS content browsing UI
Date Tue, 22 Aug 2006 21:25:14 GMT
    [ http://issues.apache.org/jira/browse/HADOOP-470?page=comments#action_12429811 ] 
eric baldeschwieler commented on HADOOP-470:

Recursive size is going to be expensive, right?   Don't think we should do that by default.


We could provide a link to do a DU to the UI.

>                 Key: HADOOP-470
>                 URL: http://issues.apache.org/jira/browse/HADOOP-470
>             Project: Hadoop
>          Issue Type: Improvement
>          Components: dfs
>            Reporter: Devaraj Das
>            Priority: Minor
> Some improvement requests from Yoram:
> 1. directory browsing: the size, replication and block size fields are unused, and indeed
the replication field contains random junk. It would be useful to use these fields to represent
the size of the folder (recursive, like du -s), and possibly the number of files in the folder.
> 2. since file sizes are typically very large, introducing a comma thousands separator
will make them more readable. 
> 3. For a particular file I have the list of blocks that make it up. It would be useful
to see the block placement information - which datanodes are holding that block. That's arguably
more relevant than the block contents when clicking on the block.
> 4. a nit - 2048 may be too small a chunk size by default. The overhead of getting the
first byte is so high (redirect, connect, handshake etc.) that you may as well get 10-20k
as your first shot.
