multi tenancy with cassandra
Since Cassandra doesn't store it's data in HDFS, is it possible to install
Cassandra on the same boxes that are running Hadoop? What I'm really asking
is, does HDFS just take over the entire disk or just a segment? Is there
something I'm missing in the understanding of HDFS? I've been thinking about
it like DOS. Is that an incorrect analogy?

HDFS is a really a filesystem on top of a traditional filesystem. HDFS is
just a folder with files in it (and this may occur on each node in your
hadoop cluster).
