Subject [jira] [Commented] (HDFS-2316) webhdfs: a complete FileSystem implementation for accessing HDFS over HTTP
Date Tue, 08 Nov 2011 00:00:57 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2316?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13145967#comment-13145967

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

@Arpit, 

I'm trying to understand -in a general way- how the additional levels indicating a class-name
(container-name) simplify the creation of XML. I've tried using json-lib JSON to XML but it
does not achieve the desired results. Futhermore, with json-lib it seems easier not have the
class-name (container-name).

Again, I mean in a 'general way'. Having a syntax that is convenient for parsing using a specific
library doesn't seem the right approach.

> 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.
