Subject [jira] [Commented] (HDFS-2316) webhdfs: a complete FileSystem implementation for accessing HDFS over HTTP
Date Tue, 08 Nov 2011 01:46:52 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2316?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13146026#comment-13146026
] 

Alejandro Abdelnur commented on HDFS-2316:
------------------------------------------

Nicholas, my concern is not regarding case sensitive or case insensitive; but regarding consistency.
In your suggested approach.

*1 path is case sensitive
*2 query parameter names are case insensitive
*3 some query parameter values are case sensitive (destination, owner, group, user.name, doAs)
*4 some query parameter values are case insensitive (override)

Note that in #3 we don't have an option as the corresponding underlying entities are case
sensitive

And I don't recall now in your proposal if 'op' is case sensitive or not.

My take is that if we are consistent, this will be easier for users. As we cannot go all case
insensitive this is why I'm suggesting all case sensitive.

> We current have hftp for accessing HDFS over HTTP.  However, hftp is a read-only FileSystem
and does not provide "write" accesses.
> In HDFS-2284, we propose to have webhdfs for providing a complete FileSystem implementation
for accessing HDFS over HTTP.  The is the umbrella JIRA for the tasks.
