CDH6.3.2 Spark ON Yarn配置使用

Posted 2023-01-16 Zakza

初始化

export SPARK_HOME=/XXXX

spark程序打包依赖分离

mvn dependency:copy-dependencies -DoutputDirectory=libs

将libs压缩为libs.zip上传到服务器或hdfs的/spark-yarn/jars

local模式配置依赖jars

mkdir -p /tmp/spark/jars
cd /tmp/spark/jars
#上传libs.zip 命令不存在yum install -y lrzsz
rz
unzip libs.zip

修改spark-defaults.conf配置，添加以下内容

#spark local jars
spark.executor.extraClassPath=/tmp/spark/jars/libs/*
spark.driver.extraClassPath=/tmp/spark/jars/libs/*

local模式执行测试

$SPARK_HOME/bin/spark-submit --master local --class com.xxx.spark.dw.dwd.DWDDebugCommonModel --driver-cores 1 --driver-memory 2G --num-executors 2 --executor-cores 2 --executor-memory 4G --name 测试 /opt/software/pkgs/xxx.jar

Client或Cluster模式配置依赖jars

快速测试client模式,将hdfs路径改为local:/tmp/spark/jars/libs

上传jars到hdfs

hdfs dfs -put /tmp/spark/jars/libs/* /spark-yarn/jars/

修改spark-defaults.conf文件将spark.yarn.jars的值改为

spark.yarn.jars=local:/opt/cloudera/parcels/CDH-6.3.2-1.cdh6.3.2.p0.1605554/lib/spark/jars/*,local:/opt/cloudera/parcels/CDH-6.3.2-1.cdh6.3.2.p0.1605554/lib/spark/hive/*,local:/tmp/spark/jars/libs/*

说明：

本地路径格式 local:/xx

hdfs路径格式 hdfs://master:8020/xx

YRAN提交任务

$SPARK_HOME/bin/spark-submit --master yarn --deploy-mode client|cluster --class com.iflytek.spark.dw.dwd.DWDDebugCommonModel  --driver-cores 1 --driver-memory 2G --num-executors 2 --executor-cores 2 --executor-memory 4G --name 测试 /opt/software/pkgs/dataoperation.jar

client模式

driver在客户端(调试)

cluster模式

driver在集群(生产)

问题说明

如果遇到local,client,cluster提交部分失败,报错java.lang.NoSuchMethodError

将spark-defaults.conf中的注释掉,只保留spark.yarn.jars,确保没有把依赖复制到spark/jars等目录

#spark local jars
#spark.executor.extraClassPath=/tmp/spark/jars/libs/*
#spark.driver.extraClassPath=/tmp/spark/jars/libs/*
