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.

Important: If you have not already done so, run -R.
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 Filesystem 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 Filesystem.

    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"
