I have also executed:

mvn dependency:tree |grep log
[INFO] |  | +- com.esotericsoftware:minlog:jar:1.3.0:compile
[INFO] +- log4j:log4j:jar:1.2.17:compile
[INFO] +- org.slf4j:slf4j-log4j12:jar:1.7.16:compile
[INFO] |  |  +- commons-logging:commons-logging:jar:1.1.3:compile


and the POM reports the above libraries.

Many Thanks for your help.

One option is to clone the class in your own project.

Experts may have better solution.

Cheers

Hi Ted,

Thanks for the promptly answer.
It is not yet clear to me what I should do.

How to fix it?

Many thanks,

In 2.0, Logging became private:

private[spark] trait Logging {

ClassNotFoundException org.apache.spark.Logging

[Carlo . Allocca]

Dear All,

I would like to ask for your help about the following issue: 
java.lang.ClassNotFoundException: org.apache.spark.Logging

I checked and the class Logging is not present.
Moreover, the line of code where the exception is thrown

final org.apache.spark.mllib.regression.LinearRegressionModel lrModel
= LinearRegressionWithSGD.train(a, numIterations, stepSize);


My POM is as reported below.


What am I doing wrong or missing? How I can fix it?

Many Thanks in advice for your support.

Best,
Carlo
