Creating CloudSolrClient Fails When Using SparkSumit

I have spark streaming program written in scala that connects to a kafka topic, reads messages, parses them into Solr documents to be added or removed from an existing collection.

My JUnits that creats an instance of the CloudSolrClient to test search queries, inserts and deletes all succeed.  However, when I integrate my program with spark and run it via sparkSubmit it fails. 

It fails in cluster mode and client mode with the same error, shown below.

It is  failing before getting to the streaming part of the progam.  It seems to be failing in this code:

HttpClientUtil.setConfigurer(new Krb5HttpClientConfigurer())
_solr = new CloudSolrClient(_zkHosts)


I even tried running that same code via the Spak-Shell.  In all cases I receive the same error:

I am using the following dependencies in my gradle.buid file:

dependencies {

compile 'org.scala-lang:scala-compiler:2.11.0'
compile 'org.scala-lang:scala-library:2.11.0'

testCompile group: 'org.scalatest', name: 'scalatest_2.11', version: '3.2.0-SNAP10'
// Use JUnit test framework
testImplementation 'junit:junit:4.12'
I am using CDH 5.10
Any help or pointer is appreciated.
