Subject [jira] [Commented] (HDFS-2316) webhdfs: a complete FileSystem implementation for accessing HDFS over HTTP
Date Fri, 09 Sep 2011 04:57:09 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2316?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13100978#comment-13100978
] 

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

@Todd, well the problem here is that we are overloading the use of a PORT for a functionality
that requires the whole domain of the namespace (in HFDS we don't have special dirs like /dev).
I'd be OK with a different port then.

@Sanjay, the in-direction for writes it would mean that we moving away from a the REST protocol,
which is a well understood and known way of interacting with resources. I think there a big
value in having a full REST API like Hoop has today.

> 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.
