Subject Re: Add jar files on classpath when submitting tasks to Spark
Date Tue, 01 Nov 2016 14:22:03 GMT
If you are using local mode then there is only one JVM. In Linux as below
mine looks like this

${SPARK_HOME}/bin/spark-submit \
                --packages ${PACKAGES} \
                --driver-memory 8G \
                --num-executors 1 \
                --executor-memory 8G \

*--master local[12] \*                --conf "${SCHEDULER}" \
                --conf "${EXTRAJAVAOPTIONS}" \
                --jars ${JARS} \
                --class "${FILE_NAME}" \
                --conf "${SPARKUIPORT}" \
                --conf "${SPARKDRIVERPORT}" \
                --conf "${SPARKFILESERVERPORT}" \
                --conf "${SPARKBLOCKMANAGERPORT}" \
                --conf "${SPARKKRYOSERIALIZERBUFFERMAX}" \
                ${JAR_FILE}

These parameters are defined below

function default_settings {
export PACKAGES="com.databricks:spark-csv_2.11:1.3.0"
export SCHEDULER="spark.scheduler.mode=FAIR"
export
EXTRAJAVAOPTIONS="spark.executor.extraJavaOptions=-XX:+PrintGCDetails
-XX:+PrintGCTimeStamps"
export
JARS="/home/hduser/jars/spark-streaming-kafka-assembly_2.11-1.6.1.jar"
export SPARKUIPORT="spark.ui.port=55555"
export SPARKDRIVERPORT="spark.driver.port=54631"
export SPARKFILESERVERPORT="spark.fileserver.port=54731"
export SPARKBLOCKMANAGERPORT="spark.blockManager.port=54832"
export SPARKKRYOSERIALIZERBUFFERMAX="spark.kryoserializer.buffer.max=512"
}

and other jar files have passed through --jars. Note that ${JAR_FILE} in my
case is built through MVN or SBT
