Hi all=2C

Hadoop have different file system(HDFS) and Cassandra have= different file system(CFS).

As Hadoop have great Eco-System (Hive{D= ataware House}=2C Hbase{Data Base} n etc..) and Cassandra(Database) it self= providing its own file system

Although =3B 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..

Please put som= e light on both of these where Hadoop overtakes Cassandra an where Cassandr= a.

And in which use cases we go for any them.


Thanks &= =3B Regards
Yogesh Kumar
