08 spark 集群搭建

Posted 2022-08-30 蓝风9

前言

呵呵 最近有一系列环境搭建的相关需求

记录一下

spark 三个节点 : 192.168.110.150, 192.168.110.151, 192.168.110.152

150 为 master, 151 为 slave01, 152 为 slave02

三台机器都做了 trusted shell

spark 版本是 spark-3.2.1-bin-hadoop2.7 

spark 集群搭建

spark 三个节点 : 192.168.110.150, 192.168.110.151, 192.168.110.152

1. 基础环境准备

192.168.110.150, 192.168.110.151, 192.168.110.152 上面安装 jdk, 上传 spark 的安装包

安装包来自于 Downloads | Apache Spark

2. spark 配置调整

复制如下 三个配置文件, 进行调整, 调整了之后 scp 到 slave01, slave02 上面 

root@master:/usr/local/ProgramFiles/spark-3.2.1-bin-hadoop2.7# cp conf/spark-defaults.conf.template conf/spark-defaults.conf
root@master:/usr/local/ProgramFiles/spark-3.2.1-bin-hadoop2.7# cp conf/spark-env.sh.template conf/spark-env.sh          
root@master:/usr/local/ProgramFiles/spark-3.2.1-bin-hadoop2.7# cp conf/workers.template conf/workers

更新 workers

# A Spark Worker will be started on each of the machines listed below.
slave01
slave02

更新 spark-defaults.conf

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              1g
# spark.executor.extraJavaOptions  -XX:+PrintGCDetails -Dkey=value -Dnumbers="one two three"

更新 spark-env.sh 

export JAVA_HOME=/usr/local/ProgramFiles/jdk1.8.0_291
export HADOOP_HOME=/usr/local/ProgramFiles/hadoop-2.10.1
export HADOOP_CONF_DIR=/usr/local/ProgramFiles/hadoop-2.10.1/etc/hadoop
export SPARK_DIST_CLASSPATH=$(/usr/local/ProgramFiles/hadoop-2.10.1/bin/hadoop classpath)
export SPARK_MASTER_HOST=master
export SPARK_MASTER_PORT=7077

3. 启动集群 

master 所在的机器执行 start-all.sh 

root@master:/usr/local/ProgramFiles/spark-3.2.1-bin-hadoop2.7# ./sbin/start-all.sh 
starting org.apache.spark.deploy.master.Master, logging to /usr/local/ProgramFiles/spark-3.2.1-bin-hadoop2.7/logs/spark-root-org.apache.spark.deploy.master.Master-1-master.out
slave01: starting org.apache.spark.deploy.worker.Worker, logging to /usr/local/ProgramFiles/spark-3.2.1-bin-hadoop2.7/logs/spark-root-org.apache.spark.deploy.worker.Worker-1-slave01.out
slave02: starting org.apache.spark.deploy.worker.Worker, logging to /usr/local/ProgramFiles/spark-3.2.1-bin-hadoop2.7/logs/spark-root-org.apache.spark.deploy.worker.Worker-1-slave02.out
root@master:/usr/local/ProgramFiles/spark-3.2.1-bin-hadoop2.7# 

测试集群

使用 spark-submit 提交 SparkPI 迭代 1000 次

spark-submit --class org.apache.spark.examples.SparkPi /usr/local/ProgramFiles/spark-3.2.1-bin-hadoop2.7/examples/jars/spark-examples_2.12-3.2.1.jar 1000

java driver 提交 spark 任务 

spark web ui 监控页面
