###Description

• A basic Java class that reads and writes in HBase @see spark.examples.HBaseUtils
• A basic java word count for spark @see spark.examples.SparkWordCount
• A basic java class that uses spark for reading and writing in HBase @see spark.examples.SparkToHBase

####How-to Optionally you'll need to set your hadoop configuration with the following commmand: export HADOOP_CONF_DIR=/etc/hadoop/conf # path to your hadoop configuration

####Run locally

• Word count java -cp ./target/hbase-spark-playground-1.0-SNAPSHOT.jar spark.examples.SparkWordCount local[1] README.md
• HBase reader java -cp ./target/hbase-spark-playground-1.0-SNAPSHOT.jar spark.examples.SparkToHBase local[1]

####Run locally with 8 cores hadoop fs -put README.md spark-submit --class spark.examples.SparkWordCount --master local[8] ./target/hbase-spark-playground-1.0-SNAPSHOT.jar local[8] README.md spark-submit --class spark.examples.SparkToHBase --master local[8] ./target/hbase-spark-playground-1.0-SNAPSHOT.jar local[8]

####Run in a yarn cluster spark-submit --class spark.examples.SparkWordCount --master yarn-cluster --executor-memory 1G --num-executors 2 ./target/hbase-spark-playground-1.0-SNAPSHOT.jar yarn-cluster README.md spark-submit --class spark.examples.SparkToHBase --master yarn-cluster --executor-memory 1G --num-executors 2 ./target/hbase-spark-playground-1.0-SNAPSHOT.jar yarn-cluster
