Question

我正在尝试在火花壳上运行我的火花应用程序。以下是我尝试过的以及在阅读此错误数小时后的更多变体......但似乎都没有效果。

spark-shell --class my_home.myhome.RecommendMatch —jars /Users/anon/Documents/Works/sparkworkspace/myhome/target/myhome-0.0.1-SNAPSHOT.jar,/Users/anon/Documents/Works/sparkworkspace/myhome/target/original-myhome-0.0.1-SNAPSHOT.jar

取而代之的是

java.lang.ClassNotFoundException: my_home.myhome.RecommendMatch
at java.net.URLClassLoader.findClass(URLClassLoader.java:381)
at java.lang.ClassLoader.loadClass(ClassLoader.java:424)

at org.apache.spark.deploy.SparkSubmit$.main(SparkSubmit.scala:126)
at org.apache.spark.deploy.SparkSubmit.main(SparkSubmit.scala)

有什么想法吗？谢谢！

更新：发现罐子必须是冒号（:)分开而不是逗号（，）分开，如几篇文章/ docs所述

spark-shell --class my_home.myhome.RecommendMatch —jars /Users/anon/Documents/Works/sparkworkspace/myhome/target/myhome-0.0.1-SNAPSHOT.jar:/Users/anon/Documents/Works/sparkworkspace/myhome/target/original-myhome-0.0.1-SNAPSHOT.jar

但是，现在错误已经改变。注意ls -la找到路径，尽管以下行抱怨不退出。奇异..

Warning: Local jar /Users/anon/Documents/Works/sparkworkspace/myhome/target/myhome-0.0.1-SNAPSHOT.jar:/Users/anon/Documents/Works/sparkworkspace/myhome/target/original-myhome-0.0.1-SNAPSHOT.jar does not exist, skipping.

To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use setLogLevel(newLevel).

更新2：

spark-shell  —class my_home.myhome.RecommendMatch —-jars “/Users/anon/Documents/Works/sparkworkspace/myhome/target/myhome-0.0.1-SNAPSHOT.jar:/Users/anon/Documents/Works/sparkworkspace/myhome/target/original-myhome-0.0.1-SNAPSHOT.jar”

上面的命令在spark-shell上产生以下内容。

Setting default log level to "WARN".
To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use    setLogLevel(newLevel).

似乎没有加载罐子:(基于我在http://localhost:4040/environment/

提供给--jars的网址必须用逗号分隔。你的第一个命令是正确的。

您还必须在最后一个参数中添加jar以进行spark-submit。可以说my_home.myhome.RecommendMatch是 myhome-0.0.1-SNAPSHOT.jar jar文件的一部分。

spark-submit --class my_home.myhome.RecommendMatch \
—jars "/Users/anon/Documents/Works/sparkworkspace/myhome/target/original-myhome-0.0.1-SNAPSHOT.jar" \ 
/Users/anon/Documents/Works/sparkworkspace/myhome/target/myhome-0.0.1-SNAPSHOT.jar

spark-shell，依赖jar和类未找到异常
