Configuring Spark on Mesos - Spark and Mesos Installed on Same Node

This topic describes the steps to configure Apache Spark on Apache Mesos when Spark and Mesos are installed on the same node.

If Spark is not installed on the same node as your Mesos slave, follow the steps at Configuring Spark on Mesos - Spark and Mesos Installed on Different Nodes.
  1. Make the following changes in SPARK_HOME/conf/
    1. Export MESOS_NATIVE_JAVA_LIBRARY, setting it to the location of the Mesos Java library.

      For example,

      export MESOS_NATIVE_JAVA_LIBRARY=/opt/mapr/mesos/mesos-1.2.0/build/src/.libs/ 
    2. Uncomment the following line from the file:
  2. If you plan to run Spark on Mesos in cluster deployment mode, copy all application files to a MapR-FS location accessible by Mesos. This includes jar and python files.

    The Spark driver does not upload local jars. The following example copies the Spark examples jar to /user/mapr in MapR-FS.

    hadoop fs -put /opt/mapr/spark/spark-2.1.0/examples/jars/spark-examples_2.11-2.1.0-mapr-SNAPSHOT.jar /user/mapr/ 
    Use the following URI to specify the location of the jar file in this example, when submitting your Spark job:
  3. Start the Mesos master.
    sudo /path/to/mesos/mesos-<version>/build/bin/ --ip=<mesos-master-node-ip> --work_dir=/var/lib/mesos 
  4. Start the Mesos agents.
    sudo /path/to/mesos/mesos-<version>/build/bin/ --master=<mesos-master-node-ip>:5050 --work_dir=/var/lib/mesos 
    Note: You can specify resource options for agents using --resources="cpus:2;dfsio_spindles:3;mem:4192"
