    具体请参看mesos+marathon+docker


    二.spark
    1.配置jdk
    JAVA_HOME=/opt/jdk
    2.安装spark
    tar -xvf spark-2.0.0-bin-hadoop2.7.tgz -C /opt/
    mv /opt/spark-2.0.0-bin-hadoop2.7 /opt/spark
    cp /opt/spark/conf/log4j.properties.template /opt/spark/conf/log4j.properties
    sed -i 's/INFO/WARN/g' /opt/spark/conf/log4j.properties
    设置spark环境变量
    cat >/etc/profile.d/spark.sh <<HERE

    export SPARK_HOME=/opt/spark

    HERE

    source /etc/profile

    root@router:~#/opt/spark/bin/

    beeline       run-example   sparkR        spark-sql     

    pyspark       spark-class   spark-shell   spark-submit 


    提示:请确保主机名可以成功解析

    pyspark

    Spark <wbr>cluster <wbr>on <wbr>Mesos

    3.配置spark集群

    http://spark.apache.org/docs/latest/running-on-mesos.html

    spark1: 192.168.8.101

    spark2: 192.168.8.102

    spark3: 192.168.8.103

    /opt/spark/sbin/start-mesos-dispatcher.sh --master mesos://zk://192.168.8.101:2181,192.168.8.102:2181,192.168.8.103:2181/mesos 

    Spark <wbr>cluster <wbr>on <wbr>Mesos

    4.提交job到spark cluster

    这里直接借用spark自带example示例

    /opt/spark/bin/spark-submit

      --class org.apache.spark.examples.SparkPi

      --master mesos://192.168.8.102:7077

      --deploy-mode cluster

      --supervise

      --executor-memory 1G

      --total-executor-cores 100

      http://192.168.8.254/ftp/examples/src/main/python/pi.py

      1000

    /opt/spark/bin/spark-submit

      --class org.apache.spark.examples.SparkPi

      --master mesos://192.168.8.102:7077

      --deploy-mode cluster

      --supervise

      --executor-memory 1G

      --total-executor-cores 100

      http://192.168.8.254/ftp/examples/jars/spark-examples_2.11-2.0.0.jar 

      1000


    提示:

    执行的job需要http://, hdfs://等形式
