what cassandra can and what can't. that's my personal thinking.
I'have just bought this book:
considering your question: My question is, can also Cassandra split a query
over the cluster like
MapReduce? and knowing the answer... as said Don Smith i suppose you are at
first chapter of the book :)

Yes, it is true, before
Solandra uses such an integration.

Hi,
we have developed a software that store logs from mail servers in MySQL,
but for huge enviroments we are developing a version that store this
data in HBase. Raw logs are, once a day, first normalized, so the output
is like this:
username,date of login, IP Address, protocol
username,date

MapReduce and Hadoop generally are pluggable so you can do queries over HDFS,
over HBase, or over Cassandra. Cassandra has good Hadoop support as outlined
here: http://wiki.apache.org/cassandra/HadoopSupport. If you're looking for a
simpler solution, there is DataStax's enterprise product
