<div dir="ltr"><div><div><div>hi there brian.<br><br></div><div>*** <br><br>1) I don't think anyone in the gluster community has done much with Cassandra on gluster. but i could be wrong. See (3) for my (postulated) reason why.<br>
<br>2) Have you considered <b>HBase</b> (which we are actively testing and playing with on many hadoop distributions) or <b>Riak</b>? Those are both much more "gluster freindly", i think, in that they have a more modular architecture. Also, because of the fact that cassandra requires ridiculously large files, I always wonder wether any file system (other than Cassandra's file system) is really *that* good of a fit.<br>
<br>3) Just my opinion, but whereas Riak has a modular storeage backend, and HBase has an abstract "org.apache.hadoop.FileSystem" interfacial backend - Cassandra sort of tries to do everything. Firstly, providing both key/value storage infrastructure, and secondly providing its own distributed file system implementation, making it a little bit more monolithic of a component in your stack.<br>
</div><div><br></div>4) FYI: We've recently setup an HBase on Gluster two node vagrant recipe. You should play with it if you get a chance: <br><br>git clone <a href="https://forge.gluster.org/vagrant/fedora19-gluster/trees/master">https://forge.gluster.org/vagrant/fedora19-gluster/trees/master</a><br>

Has anyone set up Cassandra on a Gluster file system (commit logs
disk & data disks)?<br>
<br>
If so - any recommended gluster tweaks/settings?<br>
<br>
According to Datastax - these disks should be formatted to XFS. Any
recommended settings for this?<br>
<br>
Lastly - In general has anyone used Gluster with a MySQL database
and what have they seen as performance and bottlenecks?<span class="HOEnZb"><font color="#888888"><br>
