Tsz Wo (Nicholas), SZE commented on HADOOP-2447:
------------------------------------------------

- Since we currently do not have web login, I am not sure how to make admin web 
UI working in a secure way.  Also, when adding new DFS features, we also should 
define who are allowed to perform the new operations.

- There are a few features (e.g. fsck, loglevel, etc.) which can be invoked by 
command line and web UI.  We might want to define a framework for this kind of 
dual features.

> The HDFS Namenode should be capable of limiting the total number of Inodes 
> (files + directories). The can be done through a config variable, settable in 
> hadoop-site.xml. The default should be no limit.
