spark scala maven簡單建立工程與提交任務到yarn
阿新 • • 發佈:2019-01-11
第一步 :使用idea和maven開發和打包scala和spark程式
參考:https://blog.csdn.net/xingyx1990/article/details/80752041
(注意:我自身採用mvn命令打包的方式打包:mvn clean compile package
)
第二步:其中的maven工程中需要配置java+scala的jar包的打包方式
如下,是我的spark的maven工程的pom.xml檔案
(如下的spark只是用來做spark歷史批處理測試使用,具體情況具體分析)

第三步:提交spark應用到yarn叢集
參考如下:https://www.cnblogs.com/LHWorldBlog/p/8414342.html
我的命令:
./spark-submit
--master yarn
--deploy-mode client
--queue "spark"
--class cetcocean.TestLoadDbData
SparkTest_Tank-1.0-SNAPSHOT-jar-with-dependencies.jar
不足之處:需要新增spark-submit的優化引數。
例如:
./spark-submit
--master yarn
--deploy-mode client #yarn上叢集client模式部署
--queue "spark" # 佇列名稱。在yarn下使用
--num-executors 48 #啟動的executor數量。預設為2。在yarn下使用
--driver-memory 2g # 配置成1-2g即可,一半隻是負責協調分派任務
--executor-memory 7g # 沒過executor記憶體數量
--executor-cores 3 #每個executor的核數。在yarn或者standalone下使用
SparkTest_Tank-1.0-SNAPSHOT-jar-with-dependencies.jar
