集群角色介绍:
Spark是基于内存计算的大数据并行计算框架,实际中运行计算任务肯定是使用集群模式,那么我们先来学习Spark自带的standalone集群模式了解一下它的架构及运行机制。
Standalone集群使用了分布式计算中的master-slave模型,
master是集群中含有master进程的节点
slave是集群中的worker节点含有Executor进程
●Spark架构图如下(先了解):
http://spark.apache.org/docs/latest/cluster-overview.html
集群规划 :
node001:master
node002:slave/worker
node003:slave/worker
修改配置并分发
●修改Spark配置文件
cd /export/servers/spark/conf
mv spark-env.sh.template spark-env.sh
vim spark-env.sh
#配置java环境变量
export JAVA_HOME=/export/servers/jdk1.8
#指定spark Master的IP
export SPARK_MASTER_HOST=node01
#指定spark Master的端口
export SPARK_MASTER_PORT=7077
cp slaves.template slaves
vim slaves
node002
node003
●配置spark环境变量 (建议不添加,避免和Hadoop的命令冲突) ! 不推荐添加 !
将spark添加到环境变量,添加以下内容到 /etc/profile
export SPARK_HOME=/export/servers/spark
export PATH=$PATH:$SPARK_HOME/bin
注意:
hadoop/sbin 的目录和 spark/sbin 可能会有命令冲突:
start-all.sh stop-all.sh
解决方案:
1.把其中一个框架的 sbin 从环境变量中去掉;
2.改名 hadoop/sbin/start-all.sh 改为: start-all-hadoop.sh
●通过scp 命令将配置文件分发到其他机器上
scp -r spark-2.2.0-bin-2.6.0-cdh5.14.0/ node002:$PWD
scp -r spark-2.2.0-bin-2.6.0-cdh5.14.0/ node003:$PWD
scp -r /export/servers/spark node002:$PWD
scp -r /export/servers/spark node003:$/PWD
启动 or 停止
●集群启动和停止
在主节点上启动spark集群
/export/servers/spark/sbin/start-all.sh
在主节点上停止spark集群
/export/servers/spark/sbin/stop-all.sh
●单独启动和停止 (一般 不用)
在 master 安装节点上启动和停止 master:
start-master.sh
stop-master.sh
在 Master 所在节点上启动和停止worker(work指的是slaves 配置文件中的主机名)
start-slaves.sh
stop-slaves.sh
查看web界面 :
正常启动spark集群后,查看spark的web界面,查看相关信息。

Spark中Standalone的两种提交模式(Standalone-client模式与Standalone-cluster模式)
2019-10-18 09:42:08Spark中Standalone有两种提交模式,一个是Standalone-client模式,一个是Standalone-cluster模式。 1.Standalone-client提交任务方式 提交命令 ./spark-submit --master spark://node01:7077 --class org.apache....Spark中Standalone有两种提交模式,一个是Standalone-client模式,一个是Standalone-cluster模式。
1.Standalone-client提交任务方式
提交命令
./spark-submit --master spark://node01:7077 --class org.apache.spark.examples.SparkPi ../lib/spark-examples-1.6. 0-hadoop2.6.0.jar 100 ./spark-submit --master spark://node01:7077 --deploy-mode client --class org.apache.spark.examples.SparkPi ../li b/spark-examples-1.6.0-hadoop2.6.0.jar 100

解释:–class org.apache.spark.examples.SparkPi main函数

执行原理图解
执行流程
- 1.client模式提交任务后,会在客户端启动Driver进程。
- 2.Driver会向Master申请启动Application启动的资源。
- 3.资源申请成功,Driver端将task发送到worker端执行。
- 4.worker将task执行结果返回到Driver端。
总结
- 1.client模式适用于测试调试程序。Driver进程是在客户端启动的,这里的客户端就是指提交应用程序的当前节点。在Driver端可以看到task执行的情况。生产环境下不能使用client模式,是因为:假设要提交100个application到集群运行,Driver每次都会在client端启动,那么就会导致客户端100次网卡流量暴增的问题。(因为要监控task的运行情况,会占用很多端口,如上图的结果图)客户端网卡通信,都被task监控信息占用。- 2.Client端作用
Driver负责应用程序资源的申请
任务的分发。
结果的回收。
监控task执行情况。
2.Standalone-cluster提交任务方式
提交命令
./spark-submit --master spark://node01:7077 --deploy-mode cluster --class org.apache.spark.examples.SparkPi ../lib/spark-examples-1.6.0-hadoop2.6.0.jar 100
- 1
执行原理图解
执行流程
- 1.cluster模式提交应用程序后,会向Master请求启动Driver.(而不是启动application)
- 2.Master接受请求,随机在集群一台节点启动Driver进程。
- 3.Driver启动后为当前的应用程序申请资源。Master返回资源,并在对应的worker节点上发送消息启动Worker中的executor进程。
- 4.Driver端发送task到worker节点上执行。
- 5.worker将执行情况和执行结果返回给Driver端。Driver监控task任务,并回收结果。总结
- 1.当在客户端提交多个application时,Driver会在Woker节点上随机启动,这种模式会将单节点的网卡流量激增问题分散到集群中。在客户端看不到task执行情况和结果。要去webui中看。
- 2.cluster模式适用于生产环境
- 3.Master模式先启动Driver,再启动Application。
