Subject [jira] [Commented] (HDFS-2631) Rewrite fuse-dfs to use the webhdfs protocol
Date Fri, 06 Jul 2012 23:04:35 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2631?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13408424#comment-13408424

Colin Patrick McCabe commented on HDFS-2631:
--------------------------------------------

Hi Jaimin,

I don't think we want to copy and paste all the fuse code to another directory just because
we're relying on a different backend library.  That would really increase the maintenance
burden since we'd be fixing the same bugs in two places, etc.

As Suresh said (both here and in HDFS-2656), we really do want to keep that existing API.
 fuse_dfs isn't the only libhdfs application out there!

Let me know if there's anything I can do to help, whatever that may be.  It would be really
nice to have the option of running without a JVM in libhdfs...

> We should port the implementation of fuse-dfs to use the webhdfs protocol. This has a
number of benefits:
> * Compatibility - allows a single fuse client to work across server versions
> * Works with both WebHDFS and Hoop since they are protocol compatible
> * Removes the overhead related to libhdfs (forking a jvm)
> * Makes it easier to support features like security
