YARN-cluster mode

In yarn-cluster mode, the Spark driver runs inside an application master process which is managed by YARN on the cluster, and the client can go away after initiating the application.

Estimating Pi (yarn-cluster mode):

# execute the the following command which should write the "Pi is roughly 3.1418" into the logs
# note you must specify --files argument in cluster mode to enable metrics
spark-submit \
--class org.apache.spark.examples.SparkPi \
--files $SPARK_HOME/conf/metrics.properties \
--master yarn-cluster \
--driver-memory 1g \
--executor-memory 1g \
--executor-cores 1 \
$SPARK_HOME/lib/spark-examples-1.6.0-hadoop2.6.0.jar

Estimating Pi (yarn-client mode):

# execute the the following command which should print the "Pi is roughly 3.1418" to the screen
spark-submit \
--class org.apache.spark.examples.SparkPi \
--master yarn-client \
--driver-memory 512m \
--executor-memory 256m \
--executor-cores 1 \

cd $HADOOP_PREFIX
# run the mapreduce
bin/hadoop jar share/hadoop/mapreduce/hadoop-mapreduce-examples-2.6.0.jar grep input output 'dfs[a-z.]+'

# check the output
