Spark3.1.2 Standalone高可用HA分布式部署(含pyspark）

1. 节点规划

服务	hostname	备注
master	bigdata001、bigdata002、bigdata003
slave	bigdata001、bigdata002、bigdata003
zookeeper	bigdata001、bigdata002、bigdata003	安装请参考基于Centos7分布式安装Zookeeper3.6.3
python3.9.6	bigdata001、bigdata002、bigdata003	安装请参考centos7同时安装Python2和Python3

以下操作除非特殊说明，否则都是在bigdata001上操作

2. 下载解压

[root@bigdata001 opt]#
[root@bigdata001 opt]# wget --no-check-certificate https://dlcdn.apache.org/spark/spark-3.1.2/spark-3.1.2-bin-hadoop3.2.tgz
[root@bigdata001 opt]#
[root@bigdata001 opt]# tar -zxvf spark-3.1.2-bin-hadoop3.2.tgz
[root@bigdata001 opt]#
[root@bigdata001 opt]# cd spark-3.1.2-bin-hadoop3.2/
[root@bigdata001 spark-3.1.2-bin-hadoop3.2]#

3. 修改配置

3.1 修改conf/spark-env.sh

[root@bigdata001 conf]#
[root@bigdata001 conf]# cp spark-env.sh.template spark-env.sh
[root@bigdata001 conf]#

添加内容如下：

export JAVA_HOME=/opt/jdk1.8.0_201
SPARK_MASTER_HOST=`hostname`
SPARK_MASTER_WEBUI_PORT=8060
SPARK_LOCAL_DIRS=/opt/spark-3.1.2-bin-hadoop3.2/local
SPARK_WORKER_CORES=3
SPARK_WORKER_MEMORY=6g
SPARK_DAEMON_JAVA_OPTS="-Dspark.deploy.recoveryMode=ZOOKEEPER -Dspark.deploy.zookeeper.url=bigdata001:2181,bigdata002:2181,bigdata003:2181 -Dspark.deploy.zookeeper.dir=/spark/standalone_ha"

3.2 修改conf/workers

[root@bigdata001 conf]#
[root@bigdata001 conf]# cp workers.template workers
[root@bigdata001 conf]#

内容如下：

[root@bigdata001 conf]# 
[root@bigdata001 conf]# cat workers

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

bigdata001
bigdata002
bigdata003
[root@bigdata001 conf]# 

4. 配置环境变量

在/root/.bashrc添加如下内容：

export SPARK_HOME=/opt/spark-3.1.2-bin-hadoop3.2
export PATH=$PATH:$SPARK_HOME/bin:$SPARK_HOME/sbin

执行source /root/.bashrc使环境变量生效

5. 分发spark文件

[root@bigdata001 opt]# 
[root@bigdata001 opt]# scp -r spark-3.1.2-bin-hadoop3.2/ root@bigdata002:/opt
[root@bigdata001 opt]# 
[root@bigdata001 opt]# scp -r spark-3.1.2-bin-hadoop3.2/ root@bigdata003:/opt
[root@bigdata001 opt]# 

6. 启动

1. 启动bigdata001上的master和所有的slave

[root@bigdata001 opt]#
[root@bigdata001 opt]# sh $SPARK_HOME/sbin/start-all.sh 
starting org.apache.spark.deploy.master.Master, logging to /opt/spark-3.1.2-bin-hadoop3.2/logs/spark-root-org.apache.spark.deploy.master.Master-1-bigdata001.out
bigdata001: starting org.apache.spark.deploy.worker.Worker, logging to /opt/spark-3.1.2-bin-hadoop3.2/logs/spark-root-org.apache.spark.deploy.worker.Worker-1-bigdata001.out
bigdata003: starting org.apache.spark.deploy.worker.Worker, logging to /opt/spark-3.1.2-bin-hadoop3.2/logs/spark-root-org.apache.spark.deploy.worker.Worker-1-bigdata003.out
bigdata002: starting org.apache.spark.deploy.worker.Worker, logging to /opt/spark-3.1.2-bin-hadoop3.2/logs/spark-root-org.apache.spark.deploy.worker.Worker-1-bigdata002.out
[root@bigdata001 opt]# 

2. 分别在bigdata002、bigdata003上启动standby master

[root@bigdata002 ~]# 
[root@bigdata002 ~]# /opt/spark-3.1.2-bin-hadoop3.2/sbin/start-master.sh 
starting org.apache.spark.deploy.master.Master, logging to /opt/spark-3.1.2-bin-hadoop3.2/logs/spark-root-org.apache.spark.deploy.master.Master-1-bigdata002.out
[root@bigdata002 ~]#

[root@bigdata003 ~]# 
[root@bigdata003 ~]# /opt/spark-3.1.2-bin-hadoop3.2/sbin/start-master.sh
starting org.apache.spark.deploy.master.Master, logging to /opt/spark-3.1.2-bin-hadoop3.2/logs/spark-root-org.apache.spark.deploy.master.Master-1-bigdata003.out
[root@bigdata003 ~]# 

7. 查看Web界面

查看bigdata001:8060、bigdata002:8060、bigdata003:8060界面分别如下：

8. standby master切换

现在kill掉bigdata001上的master

[root@bigdata001 opt]#
[root@bigdata001 opt]# jps
......省略部分......
3821 Master
......省略部分......
[root@bigdata001 opt]# 
[root@bigdata001 opt]# kill -9 3821
[root@bigdata001 opt]# 

再次查看bigdata002:8060，结果如下：

9. spark-shell使用

[root@bigdata001 opt]#
[root@bigdata001 opt]# $SPARK_HOME/bin/spark-shell --master spark://bigdata001:7077,bigdata002:7077,bigdata003:7077

10.PySparkShell使用
