linux上运行spark java程序

spark-submit 命令:

在spark安装目录的bin目录下有一个spark-submit脚本,可以用来提交运行spark程序

如果配置了spark的path可以直接使用spark-submit命令


编译构建spark程序

使用sbt 或者maven构建程序生成jar包
spark-submit的使用

    spark-submit \
      --class <main-class> \
      --master <master-url> \
      --deploy-mode <deploy-mode> \
      --conf <key>=<value> \
      ... # other options
      <application-jar> \
      [application-arguments]

--class: 要运行的jar包里的类,比如 test.spark.examples

--master: master的地址 比如 spark://23.195.26.187:7077

--deploy-mode: 部署模式

--conf: 运行时的一些配置 “key=value”类型

application-jar: 要运行的jar包路径,可以是hdfs:// 开头或者 file:// 开头。比如:/root/program/spark/test.jar

application-arguments: 要传给运行类主方法的参数,没有可以不传


例子

    # 本地运行,使用8个核心,传入参数100
    ./bin/spark-submit \
      --class org.apache.spark.examples.SparkPi \
      --master local[8] \
      /path/to/examples.jar \
      100
     
    # Run on a Spark standalone cluster in client deploy mode
    ./bin/spark-submit \
      --class org.apache.spark.examples.SparkPi \
      --master spark://207.184.161.138:7077 \
      --executor-memory 20G \
      --total-executor-cores 100 \
      /path/to/examples.jar \
      1000
     
    # Run on a Spark standalone cluster in cluster deploy mode with supervise
    ./bin/spark-submit \
      --class org.apache.spark.examples.SparkPi \
      --master spark://207.184.161.138:7077 \
      --deploy-mode cluster \
      --supervise \
      --executor-memory 20G \
      --total-executor-cores 100 \
      /path/to/examples.jar \
      1000
     
    # Run on a YARN cluster
    export HADOOP_CONF_DIR=XXX
    ./bin/spark-submit \
      --class org.apache.spark.examples.SparkPi \
      --master yarn \
      --deploy-mode cluster \  # can be client for client mode
      --executor-memory 20G \
      --num-executors 50 \
      /path/to/examples.jar \
      1000
     
    # Run a Python application on a Spark standalone cluster
    ./bin/spark-submit \
      --master spark://207.184.161.138:7077 \
      examples/src/main/python/pi.py \
      1000
     
    # Run on a Mesos cluster in cluster deploy mode with supervise
    ./bin/spark-submit \
      --class org.apache.spark.examples.SparkPi \
      --master mesos://207.184.161.138:7077 \
      --deploy-mode cluster \
      --supervise \
      --executor-memory 20G \
      --total-executor-cores 100 \
      http://path/to/examples.jar \
      1000


示例:

上传JAR包路径:

/root/project/test-1.0.0.jar

命令:

spark-submit --class SparkExample --master local /root/project/test-1.0.0.jar
