Hi all,
Hadoop have different file system(HDFS) and Cassandra have different 
file system(CFS).

As Hadoop have great Eco-System (Hive{Dataware House}, Hbase{Data 
Base} n etc..) and Cassandra(Database) it self providing its own file 
system

Although  we can run Hadoop's Ecosystem on Cassandra (If I am right ? 
{like pig and hive})

Hadoop have single point of Failure but Cassandra doesn't..
There are two projects in Hadoop working to avoid SPOF called HDFS HA 
and HDFS Federation.
There is a new branch called YARN which include all this.


Please put some light on both of these where Hadoop overtakes 
Cassandra an where Cassandra.
I think a more fair comparison is with HBase, not with Hadoop.
Look here

And in which use cases we go for any them.


Thanks & Regards
