Subject [jira] [Commented] (HADOOP-6253) Add a Ceph FileSystem interface.
Date Thu, 01 Dec 2011 13:06:41 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6253?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13160891#comment-13160891

Steve Loughran commented on HADOOP-6253:

I'd argue strongly against adding any more FS support explicitly into the main hadoop distribution,
purely on a test+support basis. Anything related to new filesystems are welcome, but adding
more code that will only be testable on a subset of machines is trouble. It's not going to
get tested before releases, it will ship untested with dependencies on native libraries that
most people won't have, but there is still an expectation of support.

If that's a strategy we want to take: how to get Ceph support in or near hadoop, with enough
people caring about it to keep it up to date?

> The experimental distributed filesystem Ceph does not have a single point of failure,
uses a distributed metadata cluster instead of a single in-memory server, and might be of
use to some Hadoop users.
