Subject Reading from a centralized stored
Date Tue, 06 Jan 2015 00:25:43 GMT
Hi,

I'm trying to understand how a Spark Cluster behaves when the data it is
processing resides on a centralized/remote store (S3, Cassandra, DynamoDB,
RDBMS etc).

Does every node in the cluster retrieve all the data from the central store
?

thanks
