[Hadoop-common-user] GlusterFS - is/has anybody used this?

Hello all,

I am using a Eucalyptus cloud and can get things working using
directories local to individual instances. There is an instance of
GlusterFS for the cloud. Has anyone used GlusterFS as a replacement
for HDFS? Do you sample configs? Any help anyone can give would be
great.

Does anyone have any experience with GlusterFS? Or is this a "RUN FOR
THE HILLS" type situation?
