spark3.1.2基于yarn的集群安装

• • 准备工作
  • 集群配置

wget https://www.apache.org/dyn/closer.lua/spark/spark-3.2.0/spark-3.2.0-bin-hadoop3.2.tgz -O /opt/spark-3.2.0-bin-hadoop3.2.tgz



# 创建统一目录
mkdir -p /opt/bigdata/spark

# 解压
tar xf spark-3.1.2-bin-hadoop3.2.tgz -C /opt/bigdata/spark
cd /opt/bigdata/spark/
ln -s spark-3.1.2-bin-hadoop3.2 current

# profile文件配置
export SPARK_HOME=/opt/bigdata/spark/current
export PATH=$PATH:$SPARK_HOME/bin

# 分发profile
for i in {2..5};do scp -p /etc/profile node0${i}:`pwd`;done

cd $SPARK_HOME/conf
mv spark-env.sh.template  spark-env.sh
mv spark-defaults.conf.template  spark-defaults.conf
mv workers.template workers




1. 在yarn-site.xml添加以下内容
 
    yarn.nodemanager.aux-services 
    mapreduce_shuffle,spark_shuffle 


    yarn.nodemanager.aux-services.mapreduce_shuffle.class
    org.apache.hadoop.mapred.ShuffleHandler


      yarn.nodemanager.aux-services.spark_shuffle.class
      org.apache.spark.network.yarn.YarnShuffleService

# 同步配置
for i in {2..5};do scp -p yarn-site.xml node0${i}:`pwd`;done

2. 复制Spark 对应的 jar 包放到 Hadoop 的库文件中
忘记复制此 jar 文件，那么 NodeManager 服务就无法启动
cp $SPARK_HOME/yarn/spark-3.1.2-yarn-shuffle.jar $HADOOP_HOME/share/hadoop/yarn/lib/

3. 开启 Spark 日志记录功能
cat > spark-env.sh <<-EOF
export JAVA_HOME=/usr/java/default
export HADOOP_HOME=/opt/bigdata/hadoop/current
export HADOOP_CONF_DIR=$HADOOP_HOME/etc/hadoop/
export YARN_CONF_DIR=$HADOOP_HOME/etc/hadoop/
EOF

cat > spark-defaults.conf <<-EOF
spark.shuffle.service.enabled true
# spark-history服务的配置
spark.eventLog.enabled true
spark.yarn.historyServer.address=node01:18080
spark.history.ui.port=18080
spark.eventLog.dir hdfs://mycluster/spark_log
spark.history.fs.logDirectory  hdfs://mycluster/spark_log
spark.history.retainedApplications 30
# jar包保留在hdfs,减少任务启动时间，两种方式选一个即可
#spark.yarn.jars  hdfs://mycluster/libs/spark_lib/jars/*
spark.yarn.archive   hdfs://mycluster/libs/spark_lib/lib_archive/spark-3.1.2-bin-hadoop3.2.zip
EOF

for i in {2..5};do scp spark-env.sh spark-defaults.conf node0${i}:`pwd`;done

4. 上传jar包到hdfs,加快启动速度
cd $SPARK_HOME
上传jar包到hdfs
hdfs dfs -mkdir -p /libs/spark_lib/
hdfs dfs -put jars /libs/spark_lib/
########################################
使用归档的
cd $SPARK_HOME/jars
zip spark-3.1.2-bin-hadoop3.2.zip ./*
hdfs dfs -mkdir -p /libs/spark_lib/lib_archive/
hdfs dfs -put spark-3.1.2-bin-hadoop3.2.zip /libs/spark_lib/lib_archive/
rm -f spark-3.1.2-bin-hadoop3.2.zip
###################################################

5. 同步包
cd /opt/bigdata/
[god@node01 bigdata]$ tar czf spark.gz spark
for i in {2..5};do scp -p spark.gz node0${i}:`pwd` ;done
# 解压
for i in {2..5};do ssh node0${i} "cd /opt/bigdata/ && tar xf spark.gz && rm -f spark.gz" ;done

所有NodeManager节点都要复制spark的jar包到hadoop
for i in {2..5};do ssh node0${i} "cp $SPARK_HOME/yarn/spark-3.1.2-yarn-shuffle.jar $HADOOP_HOME/share/hadoop/yarn/lib/ "; done


6. 重启yarn
[god@node01 hadoop]$ stop-yarn.sh
[god@node01 hadoop]$ start-yarn.sh

7. 启动spark history服务 选择在node03机器，任意
[god@node03 current]$ $SPARK_HOME/sbin/start-history-server.sh

8. 测试spark-shell
$SPARK_HOME/bin/spark-shell --master yarn
