Apache Spark WordCount scala example

Apache Spark is an open source cluster computing framework. Originally developed at the University of California, Berkeley's AMPLab, the Spark codebase was later donated to the Apache Software Foundation, which has maintained it since. Spark provides an interface for programming entire clusters with implicit data parallelism and fault-tolerance. Pre Requirements 1) A machine with Ubuntu 14.04 LTS operating system 2) Apache Hadoop 2.6.4 pre installed ( How to install Hadoop on Ubuntu 14.04 ) 3) Apache Spark 1.6.1 pre installed ( How to install Spark on Ubuntu 14.04 ) Spark WordCount Scala Example Step 1 - Change the directory to /usr/local/spark/sbin. $ cd /usr/local/spark/sbin Step 2 - Start all spark daemons. $ ./start-all. sh Step 3 - The JPS (Java Virtual Machine Process Status Tool) tool is limited to reporting information on JVMs for which it has the access permissions. $ jp...
