Spark2 Zeppelin interpreter dependency results in Null pointer NullPointerException - apache-spark

Question

I am trying to add dependency to Spark2 interpreter in Zeppelin as follows:
org.bdgenomics.adam:adam-core-spark2_2.11:0.23.0
There are no jars at localRepo location. So after I add this
dependency and run a simple command like println("hello world") I
am getting this NullPointerException:
java.lang.NullPointerException
at org.apache.zeppelin.spark.SparkInterpreter.open(SparkInterpreter.java:861)
at org.apache.zeppelin.interpreter.LazyOpenInterpreter.open(LazyOpenInterpreter.java:69)

at java.lang.Thread.run(Thread.java:748)
Now there are a lot of packages with jars in local-repo folder and
also under local-repo/2C4U48MY3_spark2 which is the location for
parameter zeppelin.interpreter.localRepo.
Here is zeppelin spark2 interpreter log: http://pasted.co/06cbc12a
Without this dependency, everything works fine.
I'm unable to say why I am getting this NPE. Can you help me please?
