[大数据]Spark3.x HA 集群部署

机器规模、三台机器

hadoop3.1.2

spark使用最新版本?spark-3.1.2-bin-hadoop3.2

将spark-env.sh.template 改为?spark-env.sh

将spark-defaults.conf.template 改为?spark-defaults.conf

mv spark-defaults.conf.template spark-defaults.conf
mv spark-env.sh.template spark-env.sh

vim spark-env.sh?

export JAVA_HOME=/opt/jdk1.8
export SPARK_MASTER_WEBUI_PORT=8090
export SPARK_WORKER_WEBUI_PORT=8091
export SPARK_DAEMON_JAVA_OPTS="-Dspark.deploy.recoveryMode=ZOOKEEPER
-Dspark.deploy.zookeeper.url=henghe-053:2181
-Dspark.deploy.zookeeper.dir=/spark"
export SPARK_HISTORY_OPTS="-Dspark.history.ui.port=18080 -Dspark.history.retainedApplications=30 -Dspark.history.fs.logDirectory=hdfs://henghe-052:8020/spark-log"
export HADOOP_HOME=/opt/moudle/hadoop-3.1.3
export HADOOP_CONF_DIR=/opt/moudle/hadoop-3.1.3/etc/hadoop

vim spark-defaults.conf

加上

spark.eventLog.enabled           true
spark.eventLog.dir               hdfs://henghe-052:8020/spark-log
spark.yarn.historyServer.address=henghe-052:18080
spark.history.ui.port=18080

将sbin/start-all.sh 改个名字和hadoop的start-all.sh重名了，启动可能出问题

mv start-all.sh start-spark-all.sh

henghe-052启动

sbin/start-spark-all.sh

?在henghe-051单独启动master

?在spark-web ui查看

启动history,前提是在hdfs已经建好了history目录

sbin/start-history-server.sh

?查看界面：hengeh-052:18080

?跑个案例验证下集群功能

 bin/spark-submit  --class org.apache.spark.examples.SparkPi --master spark://henghe-052:7077 ./examples/jars/spark-examples_2.12-3.1.2.jar 10

跑成功

单独启动worker命令

sbin/start-worker.sh ?spark://henghe-052:7077

sbin/start-worker.sh ?spark://henghe-052:7077
