Subject [jira] [Commented] (HDFS-2316) webhdfs: a complete FileSystem implementation for accessing HDFS over HTTP
Date Fri, 09 Sep 2011 16:19:09 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2316?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13101305#comment-13101305
] 

Sanjay Radia commented on HDFS-2316:
------------------------------------

> If we use a webhdfs://HOST:PORT from the FS client impl and internally we replace to
it to
> http://HOST:PORT/webhdfs, I'd live with that one. After all (as Todd pointed offline)
it is not fully REST.
That is exactly what Nicholas has implemented. ie with curl you use the url http://host/:port/webhdfs.

hdfs://host:port/path and webhdfs://hostx:portx/path  are consistent wrt to the path.
While it would nice to be consistent for http, we cannot because of other services using the
same port.
So I think we have an agreement on this.

> 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.
