一、下载和解压
https://archive.apache.org/dist/spark/spark-2.3.1/
tar zxv -f spark-2.3.1-bin-hadoop2.7.tgz mv spark-2.3.1-bin-hadoop2.7/ spark-2.3.1
二、配置
2.1、配置 spark-default.conf,按需调整
spark.eventLog.enabled true spark.eventLog.dir hdfs://myha01/user/spark/eventLogs spark.eventLog.compress true spark.history.fs.logDirectory hdfs://myha01/user/spark/eventLogs spark.yarn.historyServer.address ds075:18080 spark.serializer org.apache.spark.serializer.KryoSerializer spark.master yarn spark.driver.cores 2 spark.driver.memory 5g spark.executor.cores 2 spark.executor.memory 4g spark.executor.instances 4 spark.sql.warehouse.dir hdfs://myha01/user/hive/warehouse # 用来存放spark的依赖jar包 spark.yarn.jars=hdfs://myha01/user/spark/spark_jars/*
-
spark.eventLog.enabled:设置true开启日志记录.
-
spark.eventLog.dir:存储日志路径,Application 在运行过程中所有的信息均记录在该属性指定的路径下,我这里设置的是 hdfs 路径(也可以是本地路径如file:///val/log/sparkEventLog)
-
spark.yarn.historyServer.address:设置 History Server 的地址和端口,这个链接将会链接到 YARN 检测界面上的 Tracking UI
-
spark.history.fs.logDirectory:日志目录和 spark.eventLog.dir 保持一致,Spark History Server 页面只展示该指定路径下的信息
-
spark.eventLog.compress:是否压缩记录Spark事件信息,前提spark.eventLog.enabled 为 true,默认使用的是snappy
2.2、配置 spark-env.sh
export JAVA_HOME=/usr/local/jdk1.8.0_231 export HADOOP_HOME=/home/hadoop/hadoop-2.9.2 export HADOOP_CONF_DIR=${HADOOP_HOME}/etc/hadoop export SPARK_MASTER_IP=ds072 # spark 日志保存时间 export SPARK_HISTORY_OPTS="-Dspark.history.retainedApplications=10"
2.3、配置 slaves
cp slaves.template slaves vim slaves
在文件末尾直接添加配置内容即可,配置示例如下:
2.4、创建目录
hdfs dfs -mkdir -p /user/spark/jobs/history hdfs dfs -mkdir -p /user/spark/spark_jars hdfs dfs -mkdir -p /user/spark/eventLogs
spark-defaults.conf 中配置的目录,用来存放 spark 的依赖jar包,需要进入 Spark 的 jars 目录,执行如下命令上传 jar 包:
hdfs dfs -put ./* /user/spark/spark_jars
2.5、拷贝到其他节点
scp -r spark-2.3.1 ds073:/home/hadoop scp -r spark-2.3.1 ds074:/home/hadoop scp -r spark-2.3.1 ds075:/home/hadoop
2.6、配置环境变量
vim ~/.bashrc # spark export SPARK_HOME=/home/hadoop/spark-2.3.1 export PATH=$PATH:$SPARK_HOME/bin source ~/.bashrc
三、启动与测试
3.1、启动 Standalone 模式
${SPARK_HOME}/sbin/start-all.sh
然后登陆 8080 页面查看 ui,如果访问不了可以查看日志确定失败原因。
测试一下 Standalone 模式:
spark-submit \ --class org.apache.spark.examples.SparkPi \ --master spark://ds072:7077 \ ${SPARK_HOME}/examples/jars/spark-examples_2.11-2.3.1.jar 100
3.2、 启动 spark 的 history-server
3.3、测试 Yarn 模式
spark-shell --master yarn-client
如果有报错类似:
Caused by: java.io.IOException: Failed to send RPC 6405368361626935580 to /192.168.11.73:31107: java.nio.channels.ClosedChannelException

java.lang.IllegalStateException: Spark context stopped while waiting for backend
在 yarn.xml 中添加如下配置:
<property> <name>yarn.nodemanager.pmem-check-enabled</name> <value>false</value></property><property> <name>yarn.nodemanager.vmem-check-enabled</name> <value>false</value></property>
也可以运行如下:
spark-submit \ --class org.apache.spark.examples.SparkPi \ --master yarn \ ${SPARK_HOME}/examples/jars/spark-examples_2.11-2.3.1.jar 10
