Subject [jira] [Commented] (HDFS-2316) webhdfs: a complete FileSystem implementation for accessing HDFS over HTTP
Date Thu, 08 Sep 2011 23:48:10 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2316?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13100797#comment-13100797
] 

Eli Collins commented on HDFS-2316:
-----------------------------------

I definitely agree with these distinct use cases, I'm just wondering if we need to have two
separate FileSystem over HTTP implementations vs one client that may or may not use a proxy
server (there's no reason http or FileSystem clients need to care whether they're being proxied).
Sounds like we were duplicating code w/o understanding what could be shared. You and Alejandro
have looked at the specifics more than I have so I trust your judgement.

> 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.
