Subject [jira] Updated: (HADOOP-6253) Add a Ceph FileSystem interface.
Date Thu, 05 Nov 2009 19:45:32 GMT

Gregory Farnum updated HADOOP-6253:
-----------------------------------

    Attachment: HADOOP-6253.patch

Okay; I've rewritten the IOStreams and re-architected the code to support pluggable Ceph instances,
which allows me to write a CephFaker running on the LocalFS. Doing so it passes all the unit
tests in FileSystemBaseContractTest.
I've also added in uses of the Hadoop logging framework but don't have a good feel for what
level of output that should be generating, so I'd especially appreciate somebody looking at
that.

and might be of use to some Hadoop users.
