Subject Hadoop over Cassandra
Date Mon, 17 May 2010 19:41:27 GMT
Can someone explain how this works? As long as I know, there is no execution
engine in Cassandra alone, so I assume that Hadoop gives the MapReduce
execution engine which uses Cassandra as the distributed storage? Is data
locality preserved? How mature this "couple" is? How is the performance of
this compared to the original Hadoop over HDFS?
