数据建设实践之大数平台(六)安装spark

安装spark

上传安装包到/opt/software目录并解压

bash 复制代码

[bigdata@node101 software]$ tar -xvf spark-3.3.1-bin-hadoop3.tgz -C /opt/services/ 
[bigdata@node101 software]$ tar -xvf spark-3.3.1-bin-without-hadoop.tgz -C /opt/services/

重命名文件

bash 复制代码

[bigdata@node101 services]$ mv spark-3.3.1-bin-hadoop3 spark-3.3.1

配置环境变量

bash 复制代码

[bigdata@node101 ~]$ sudo vim /etc/profile.d/bigdata_env.sh

bash 复制代码

export SPARK_HOME=/opt/services/spark-3.3.1
export PATH=$PATH:$JAVA_HOME/bin:$ZK_HOME/bin:$HADOOP_HOME/bin:$HADOOP_HOME/sbin:$HIVE_HOME/bin:$SPARK_HOME/bin

分发环境变量

bash 复制代码

[bigdata@node101 ~]$ sudo ./bin/xsync /etc/profile.d/bigdata_env.sh

刷新环境变量，5台机器上执行

bash 复制代码

[bigdata@node101 ~]$ source /etc/profile

配置spark-env.sh

bash 复制代码

export SPARK_DIST_CLASSPATH=$(hadoop classpath)
export SPARK_HISTORY_OPTS=" 
-Dspark.history.ui.port=18080  
-Dspark.history.fs.logDirectory=hdfs://mycluster:8020/spark-history  
-Dspark.history.retainedApplications=30"

配置spark-defaults.conf

bash 复制代码

[bigdata@node101 conf]$ cp spark-defaults.conf.template  spark-defaults.conf

bash 复制代码

spark.master                       yarn
spark.eventLog.enabled             true
spark.eventLog.dir                 hdfs://mycluster:8020/spark-history
spark.serializer                   org.apache.spark.serializer.KryoSerializer
#启动动态分配
spark.dynamicAllocation.enabled    true
#启用Spark shuffle服务
spark.shuffle.service.enabled    true
#Executor个数初始值
spark.dynamicAllocation.initialExecutors    1
#Executor个数最小值
spark.dynamicAllocation.minExecutors    1
#Executor个数最大值
spark.dynamicAllocation.maxExecutors    6
#Executor空闲时长，若某Executor空闲时间超过此值，则会被关闭
spark.dynamicAllocation.executorIdleTimeout    60s
#积压任务等待时长，若有Task等待时间超过此值，则申请启动新的Executor
spark.dynamicAllocation.schedulerBacklogTimeout    1s
#spark shuffle老版本协议
#spark.shuffle.useOldFetchProtocol true
spark.yarn.historyServer.address=node101:18080
spark.history.ui.port=18080
spark.history.fs.logDirectory=hdfs://mycluster:8020/spark-history

hdfs上创建日志文件

bash 复制代码

[bigdata@node101 conf]$ hdfs dfs -mkdir /spark-history

上传spark-defaults.conf到hive目录下

bash 复制代码

[bigdata@node101 conf]$cp $SPARK_HOME/conf/spark-defaults.conf $HIVE_HOME/conf/

上传hive-exec-3.1.3.jar到纯净版

bash 复制代码

[bigdata@node101 conf]$cp $HIVE_HOME/lib/hive-exec-3.1.3.jar /opt/services/spark-3.3.1-bin-without-hadoop/jars/

上传spark-3.3.1-yarn-shuffle.jar

bash 复制代码

[bigdata@node101 conf]$ cp $SPARK_HOME/yarn/spark-3.3.1-yarn-shuffle.jar  /opt/services/hadoop-3.3.5/share/hadoop/yarn/lib/

上传spark jar包到hdfs

bash 复制代码

[bigdata@node101 spark-3.3.1-bin-without-hadoop]$ hdfs dfs -mkdir /spark-jars          
 
[bigdata@node101 spark-3.3.1-bin-without-hadoop]$ hdfs dfs -put ./jars/* /spark-jars

启动历史服务

bash 复制代码

[bigdata@node101 spark-3.3.1]$ sbin/start-history-server.sh
