Subject [jira] [Commented] (HADOOP-6253) Add a Ceph FileSystem interface.
Date Thu, 01 Dec 2011 20:12:41 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6253?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13161097#comment-13161097
] 

Jakob Homan commented on HADOOP-6253:
-------------------------------------

bq. One of the comments made by another file system vendor that we've spoken too is that there
are too many "if (HDFS) do this else do this" that undercut the capabilities of non-HDFS implementations.
I wouldn't be too surprised if Ceph has the same problem.

Those should be removed and we'd of course be happy to accept patches to do so.  I also agree
(-0).  A Ceph impl will require and deserve more attention than we can expect to be able to
give (based on past experience).

> 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.
