Incompatibility in Spark 2.1.6

[hi-T0day]

Hello!
I meet up a error when I run the spark_dbscan in Spark 2.1.6.
The error is
java.lang.NoClassDefFoundError: org/apache/spark/Logging
Caused by: java.lang.ClassNotFoundException: org.apache.spark.Logging
Spark 2.0 removes the org.apache.spark.Logging. So spark_dbscan cannot running.
Any solution to this problem?
I have tried to change the other dependencies, but still failed.

Had the same Exception, I had to update the Spark dependency in the build.gradle of the library to make it work. You'll need to clone the repo and update it with the same version you're using on your cluster, or you can directly get my fork if that's easier.

use org.apache.spark.internal.Logging instead org.apache.spark.Logging

@csbenz your fork works only with Spark 1.6.2 and I can't find build.gradle (there's only build.sbt). Am I missing something?

Can anyone elaborate on their solution to this problem? I'm running Spark 2.3.0

you can solve this problem the following steps.
step1: you must create a new package started with 'org.apache.spark' ,such as 'org.apache.spark.external'
step2: Creating a trait extends the 'org.apache.spark.internal.Logging' trait ,Note that the access modifier must be public
step3 : now you can access the new trait
