CodePudding user response：

This issue seems like you are submitting your application in distributed environment. and the application is not able to find the dependency in the class-path.

You need to add the required jars in the class-path. You may use below option in spark-submit command to add the jar files in class-path.

--jars /path/to/first.jar,/path/to/second.jar,/path/to/third.jar

It worked by just adding the blas and lapack dependencies to pom.xml file. Thanks a lot for your answers.
