Although, HBase vs Cassandra is a fair comparison. You can have a look at this comparison: http://bigdatanoob.blogspot.com/2012/11/hbase-vs-cassandra.html HTH, Anil Gupta On Thu, Dec 6, 2012 at 11:27 AM, Colin McCabe <cmcc...@alumni.cmu.edu> wrote: On Thu, Dec 6, 2012 at 8:55 AM, yogesh dhari <yogeshdh...@live.com> wrote: > 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.. > > Please put some light on both of these where Hadoop overtakes Cassandra an > where Cassandra. > > And in which use cases we go for any them. As Harsh commented, HDFS doesn't have a single point of failure any more. Hadoop and Cassandara are not really competitors. You can run Hadoop on top of Cassandra if you want. It's possible to compare Cassandra and HBase, and some people have done so. In general, I've been told that Cassandra is a better match for situations where you write more than you read, and you don't care about data consistency. But that might be a better question for the HBase and/or Cassandra mailing lists. cheers, Colin -- Thanks & Regards, Anil Gupta
