Spark behavior on native file system

Spark behavior on native file system

We are experimenting to run Spark in our project without Hadoop and no distributed storage like HDFS. Spark is installed on a single node with 10 Cores and 16GB RAM and this node is not part of any cluster. Assuming Spark driver takes 2 cores and the rest of them are consumed by executors(2 each) at the time of execution.

If we process a big CSV file (of size 1 GB) stored in local disk in Spark as RDD and repartition it to 4 different partitions, will executors process each partition in parallel? What would executors do if we don't repartition the RDD to 4 diff partitions? Do we loose the power of distributed computing and parallelism if dont use HDFS?

How To Start with Apache Spark and Apache Cassandra

Apache Cassandra is a specific database that scales linearly. This has its price: specific table modelling, configurable consistency and limited analytics. Apple performs millions of operations per second on over 160,000 Cassandra instances while collecting over 100 PBs of data. You can bypass these limited analytics with the Apache Spark and the DataStax connector, and that’s what the story is about.
