Thanks a lot Sean.
Yeah I am contemplating to choose the right technology as my
recommendation engine is scaling up. It is not working well with my
FileDataModel now. If using hadoop alone can help, then I will go for
the most natural way.
Another question can I use the taste-web along with Hadoop only?
Thanks.

I haven't used Brisk, but doubt there would be any real difference for
your use case. Hadoop's integration with Cassandra is fairly light and
arms-length, so the details of the Cassandra distro behind it ought
not matter too much.
Cassandra isn't the most natural choice as a Hadoop data store, but it
can be made to work. If you're choosing tools from scratch, just using
HDFS as your data store is probably more natural.
Mahout has virtually no direct relationship to Cassandra, so the same
comments apply even more as regards Brisk vs vanilla Cassandra and
Mahout. It should not matter much if at all.
The only direct integration with Cassandra is in the non-distributed
Recommender, where I cobbled together a CassandraDataModel for an
article I wrote
(http://www.acunu.com/blogs/sean-owen/recommending-cassandra/).
Mahout doesn't use Cassandra directly when using Hadoop, but you can
modify it to work with Cassandra as an InputFormat. Again,
conveniently, I wrote about that recently for Acunu:

Hello,
I am planning to use Mahout with Hadoop and Cassandra as datastore. I have
been reading about the goodness of using Brisk. Can we use Mahout with Brisk
as is from the package like how we implement it with Hadoop and Cassandra?
Whats the difference of using Brisk and a combination of Hadoop and
Cassandra?
thanks.
