java.lang.NoSuchMethodError in databricks

[sarvesh242]

I have created a package in scala. Now, I am calling a method from that package and using it in my notebook. During run time, it throws me an error java.lang.NoSuchMethodError. The method exists in the package but still, I am getting this error. Please guide me regarding the same.

Hi @sarvesh gakhar​ , Can you please check the scala version?

scala version 2.11 with spark 2.4.3

Hi @sarvesh gakhar​ , The exception often arises if you mix different scala versions. Do you have any dependencies loaded for scala 2.11?

Please check if you have some libraries installed on your cluster that probably used Scala 2.11.

Hi! @Kaniz Fatma​ . I am using dependencies for scala 2.11. Can you please elaborate on the above point

"mixing different scala versions".

Thanks

Hi @sarvesh gakhar​ , I meant Spark and Scala version mismatch.

Hi! @Kaniz Fatma​ . I am using scala version 2.11 with spark 2.4.3.

According to Apache spark official website 😞https://spark.apache.org/docs/2.4.3/#:~:text=For%20the%20Scala%20API%2C%20Spark,x.)

Spark 2.4.3 uses Scala 2.12.

(https://spark.apache.org/docs/2.4.0/#:~:text=For%20the%20Scala%20API%2C%20Spark,0%20uses%20Scala%202....)

 Spark 2.4. 0 uses Scala 2.11.

I have two options with respect to Spark/scala version. Does any option has edge over the other ?

Thanks!
