mesos集群部署参见上篇。
运行在mesos上面和 spark standalone模式的区别是：
1）stand alone
需要自己启动spark master
需要自己启动spark slaver（即工作的worker）
2）运行在mesos
启动mesos master
启动mesos slaver
启动spark的 ./sbin/start-mesos-dispatcher.sh -m mesos://127.0.0.1:5050
配置spark的可执行程序的路径(也就是mesos里面所谓EXECUTOR)，提供给mesos下载运行。
在mesos上面的运行流程：
1）通过spark-submit提交任务到spark-mesos-dispatcher
2）spark-mesos-dispatcher 把通过driver 提交到mesos master，并收到任务ID
3）mesos master 分配到slaver 让它执行任务
4) spark-mesos-dispatcher，通过任务ID查询任务状态
前期配置：
1) spark-env.sh
配置mesos库，以及spark可以执行的二进制程序包（这里偷懒用了官网的包，这里URI支持hdfs，http）。
#到spark的安装目录 vim conf/spark-env.sh # Options read by executors and drivers running inside the cluster # - SPARK_LOCAL_IP, to set the IP address Spark binds to on this node # - SPARK_PUBLIC_DNS, to set the public DNS name of the driver program # - SPARK_CLASSPATH, default classpath entries to append # - SPARK_LOCAL_DIRS, storage directories to use on this node for shuffle and RDD data # - MESOS_NATIVE_JAVA_LIBRARY, to point to your libmesos.so if you use Mesos MESOS_NATIVE_JAVA_LIBRARY=/usr/local/lib/libmesos.so SPARK_EXECUTOR_URI=http://d3kbcqa49mib13.cloudfront.net/spark-1.5.1-bin-hadoop2.6.tgz
2）spark-defaults.conf
# Default system properties included when running spark-submit. # This is useful for setting default environmental settings. # Example: # spark.master spark://master:7077 # spark.eventLog.enabled true # spark.eventLog.dir hdfs://namenode:8021/directory # spark.serializer org.apache.spark.serializer.KryoSerializer # spark.driver.memory 5g # spark.executor.extraJavaOptions -XX:+PrintGCDetails -Dkey=value -Dnumbers="one two three" spark.executor.uri http://d3kbcqa49mib13.cloudfront.net/spark-1.5.1-bin-hadoop2.6.tgz spark.master mesos://10.230.136.197:5050
3) 修改测试WordCount.java
这里测试例子，可以参考 提交任务到spark。
/** * Illustrates a wordcount in Java */ package com.oreilly.learningsparkexamples.mini.java; import java.util.Arrays; import java.util.List; import java.lang.Iterable; import scala.Tuple2; import org.apache.commons.lang.StringUtils; import org.apache.spark.SparkConf; import org.apache.spark.api.java.JavaRDD; import org.apache.spark.api.java.JavaPairRDD; import org.apache.spark.api.java.JavaSparkContext; import org.apache.spark.api.java.function.FlatMapFunction; import org.apache.spark.api.java.function.Function2; import org.apache.spark.api.java.function.PairFunction; public class WordCount { public static void main(String[] args) throws Exception { String inputFile = args[0]; String outputFile = args[1]; // Create a Java Spark Context. SparkConf conf = new SparkConf().setMaster("mesos://10.230.136.197:5050").setAppName("wordCount").set("spark.executor.uri", "http://d3kbcqa49mib13.cloudfront.net/spark-1.5.1-bin-hadoop2.6.tgz"); JavaSparkContext sc = new JavaSparkContext(conf); // Load our input data. JavaRDD<String> input = sc.textFile(inputFile); // Split up into words. JavaRDD<String> words = input.flatMap( new FlatMapFunction<String, String>() { public Iterable<String> call(String x) { return Arrays.asList(x.split(" ")); }}); // Transform into word and count. JavaPairRDD<String, Integer> counts = words.mapToPair( new PairFunction<String, String, Integer>(){ public Tuple2<String, Integer> call(String x){ return new Tuple2(x, 1); }}).reduceByKey(new Function2<Integer, Integer, Integer>(){ public Integer call(Integer x, Integer y){ return x + y;}}); // Save the word count back out to a text file, causing evaluation. counts.saveAsTextFile(outputFile); } }
进入到examples/mini-complete-example 中，重新编译生成jar包。
4）启动spark-mesos-dispather
./sbin/start-mesos-dispatcher.sh -m mesos://10.230.136.197:5050

5)提交任务
./bin/spark-submit --master mesos://10.230.136.197:7077 --deploy-mode cluster --class com.oreilly.learningsparkexamples.mini.java.WordCount /home/qingpingzhang/dev/spark-1.5.1-bin-hadoop2.6/examples/mini-complete-example/target/learning-spark-mini-example-0.0.1.jar /home/qingpingzhang/dev/spark-1.5.1-bin-hadoop2.6/README.md /home/qingpingzhang/dev/spark-1.5.1-bin-hadoop2.6/wordcounts.txt
然后我们可以看到mesos-master的输出，收到任务，然后发送给slaver，最后更新任务状态：

那么这个问题咋解决呢？
去mesos的slaver上面查看运行日志（默认是在/tmp/mesos/slaves/目录下），发现尼玛，这个跟stand alone还不一样（stand alone模式下面，spark的master会建立一个http server，把jar包提供给spark worker下载执行，但是mesos模式居然不是这样，jar包需要是放到hdfs 或者http 路径下面？坑爹了），这有点不合理啊，亲。

好吧，为了能够跑通测试，现在把jar包和readme.txt文件copy到mesos slaver的机器上面去。

至此，spark 运行在mesos框架上也算是跑通了。
这里没有把mesos，spark的webui 中的图贴出来。
总结一下：
1）搭建好mesos集群
2）安装好spark，启动spark的mesos-dispather（连接到mesos的matser上）
3）采用spark-submit来提交任务（提交任务的时候，需要把jar包放到可以下载的地方，例如：hdfs，http等）
-----------------
使用mesos的好处，主要是能够动态的启动和分配任务，尽量利用好机器资源。
由于我们的日志分析就2台机器，所以还是打算用spark的stand alone 模式启动。
