环境:

CentOS 7

spark-2.0

jdk-1.8

mesos-1.0

一.mesos

zk1: 192.168.8.101

zk2: 192.168.8.102

zk3: 192.168.8.103

mesos-m1: 192.168.8.101

具体请参看mesos+marathon+docker

二.spark

1.配置jdk

略

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

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 

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
