卧疾丰暇豫,翰墨时间作。这篇文章主要讲述HA-Spark集群环境搭建(Yarn模式)相关的知识,希望能为你提供帮助。
前置准备【HA-Spark集群环境搭建(Yarn模式)】CentOS7、jdk1.8、scala-2.11.12、spark-2.4.5、hadoop-2.7.7、zookeeper-3.5.7
想要完成本期视频中所有操作,需要以下准备:
一、集群规划
二、集群配置 2.1 spark-env.sh
[xiaokang@hadoop01 conf]$ cp spark-env.sh.template spark-env.sh
export java_HOME=/opt/moudle/jdk1.8.0_191
export SCALA_HOME=/opt/moudle/scala-2.11.12
YARN_CONF_DIR=/opt/software/hadoop-2.7.7/etc/hadoop
export SPARK_DAEMON_JAVA_OPTS="-Dspark.deploy.recoveryMode=ZOOKEEPER -Dspark.deploy.zookeeper.url=hadoop01:2181,hadoop02:2181,hadoop03:2181 -Dspark.deploy.zookeeper.dir=/ha-spark"
export SPARK_HISTORY_OPTS="-Dspark.history.ui.port=18080 -Dspark.history.retainedApplications=24 -Dspark.history.fs.logDirectory=hdfs://hadoop01:9000/spark-jobhistory"
2.2 spark-defaults.conf
[xiaokang@hadoop01 conf]$ cp spark-defaults.conf.template spark-defaults.conf
#spark.masterspark://hadoop01:7077
spark.masterspark://hadoop01:7077,hadoop02:7077
spark.eventLog.enabledtrue
spark.eventLog.dirhdfs://hadoop01:9000/spark-jobhistory
spark.yarn.historyServer.addresshadoop01:18080
2.3 slaves
[xiaokang@hadoop01 conf]$ cp slaves.template slaves
hadoop01
hadoop02
hadoop03
2.4 yarn-site.xml
< !-- 由于测试环境的虚拟机内存太少, 防止将来任务被意外杀死, 做如下配置 -->
< !--是否启动一个线程检查每个任务正使用的物理内存量,如果任务超出分配值,则直接将其杀掉,默认是true -->
< property>
< name> yarn.nodemanager.pmem-check-enabled< /name>
< value> false< /value>
< /property>
< !--是否启动一个线程检查每个任务正使用的虚拟内存量,如果任务超出分配值,则直接将其杀掉,默认是true -->
< property>
< name> yarn.nodemanager.vmem-check-enabled< /name>
< value> false< /value>
< /property>
< property>
< name> yarn.log.server.url< /name>
< value> http://hadoop01:19888/jobhistory/logs< /value>
< /property>
2.5 分发
[xiaokang@hadoop01 ~]$ distribution.sh /opt/software/spark-2.4.5
[xiaokang@hadoop01 ~]$ distribution.sh /opt/software/hadoop-2.7.7/etc/hadoop/yarn-site.xml
三、启动集群 3.1 启动ha-hadoop集群
[xiaokang@hadoop01 ~]$ ha-hadoop.sh start
3.2 在hadoop01上启动spark集群
# 进入/opt/software/spark-2.4.5/sbin目录并启动集群
[xiaokang@hadoop01 sbin]$ ./start-all.sh
3.3 在hadoop02上启动备Master
# 进入/opt/software/spark-2.4.5/sbin目录并启动备Master
[xiaokang@hadoop02 sbin]$ ./start-master.sh
3.4 在hadoop01上启动任务历史服务器
# 进入/opt/software/spark-2.4.5/sbin目录并启动任务历史服务器
[xiaokang@hadoop01 sbin]$ ./start-history-server.sh
四、查看集群 4.1 jps进程查看
[xiaokang@hadoop01 ~]$ call-cluster.sh jps
--------hadoop01--------
10881 NodeManager
11265 HistoryServer
13058 Master
10131 NameNode
10470 JournalNode
11176 Worker
10250 DataNode
10683 DFSZKFailoverController
10796 JobHistoryServer
12973 Jps
9935 QuorumPeerMain
--------hadoop02--------
7232 QuorumPeerMain
7648 DFSZKFailoverController
7505 JournalNode
7831 NodeManager
8183 Worker
7321 NameNode
7402 DataNode
9099 Jps
7743 ResourceManager
8255 Master
--------hadoop03--------
7313 DataNode
8273 Jps
7234 QuorumPeerMain
7843 Worker
7545 ResourceManager
7419 JournalNode
7663 NodeManager
4.2 Web UI查看
[xiaokang@hadoop01 sbin]$ cat /opt/software/spark-2.4.5/logs/spark-xiaokang-org.apache.spark.deploy.master.Master-1-hadoop01.out | grep MasterWebUI
20/05/31 08:32:08 INFO MasterWebUI: Bound MasterWebUI to 0.0.0.0, and started at http://hadoop01:8081
通过启动日志可以看到hadoop01的?
?MasterWebUI?
?的端口号为8081[xiaokang@hadoop02 sbin]$ cat /opt/software/spark-2.4.5/logs/spark-xiaokang-org.apache.spark.deploy.master.Master-1-hadoop02.out | grep MasterWebUI
20/05/31 08:32:43 INFO MasterWebUI: Bound MasterWebUI to 0.0.0.0, and started at http://hadoop02:8082
通过启动日志可以看到hadoop02的?
?MasterWebUI?
?的端口号为8082文章图片
hadoop01上的任务历史服务器端口号为18080
五、计算 PI (测试高可用)
[xiaokang@hadoop01 ~]$ spark-submit --master yarn --class org.apache.spark.examples.SparkPi /opt/software/spark-2.4.5/examples/jars/spark-examples_2.11-2.4.5.jar 1000
运行过程中将主Master给kill掉,测试是否高可用
[xiaokang@hadoop01 ~]$ kill -9 11091
杀掉主Master之后,程序还是同样在执行,可以看到hadoop02的?
?MasterWebUI?
?中状态显示为recovering最终计算结果如下:
通过hadoop03上YARN的?
?8088?
?可以查看历史任务推荐阅读
