Scala Package Issue With ZKStringSerializer - scala

Question

I am trying to use the class ZKStringSerializer, which I get with
import kafka.utils.ZKStringSerializer
According to the entirety of the internet, and even my own code before I restarted by computer, this should allow my code to work. However, I now get an incredibly confusing compile error,
object ZKStringSerializer in package utils cannot be accessed in package kafka.utils
This is confusing because this file is not supposed to be in any package, and I don't specify a package anywhere. This is my code:
import org.apache.spark.sql.SparkSession
import org.apache.spark.sql.functions._
import org.apache.log4j.{Level, Logger}
import org.apache.spark.sql.execution.streaming.FileStreamSource.Timestamp
import org.apache.spark.sql.types._
import org.I0Itec.zkclient.ZkClient
import org.I0Itec.zkclient.ZkConnection
import java.util.Properties
import org.apache.kafka.clients.admin
import kafka.admin.{AdminUtils, RackAwareMode}
import kafka.utils.ZKStringSerializer
import kafka.utils.ZkUtils
import org.apache.kafka.clients.producer.{KafkaProducer, ProducerRecord}
object SpeedTester {
def main(args: Array[String]): Unit = {
val spark = SparkSession.builder.master("local[4]").appName("SpeedTester").config("spark.driver.memory", "8g").getOrCreate()
val rootLogger = Logger.getRootLogger()
rootLogger.setLevel(Level.ERROR)
import spark.implicits._
val zookeeperConnect = "localhost:2181"
val sessionTimeoutMs = 10000
val connectionTimeoutMs = 10000
val zkClient = new ZkClient(zookeeperConnect, sessionTimeoutMs, connectionTimeoutMs, ZKStringSerializer)
val topicName = "testTopic"
val numPartitions = 8
val replicationFactor = 1
val topicConfig = new Properties
val isSecureKafkaCluster = false
val zkUtils = new ZkUtils(zkClient, new ZkConnection(zookeeperConnect), isSecureKafkaCluster)
AdminUtils.createTopic(zkUtils, topicName, numPartitions, replicationFactor, topicConfig)
// Create producer for topic testTopic and actually push values to the topic
val props = new Properties()
props.put("bootstrap.servers", "localhost:9592")
props.put("key.serializer", "org.apache.kafka.common.serialization.StringSerializer")
props.put("value.serializer", "org.apache.kafka.common.serialization.StringSerializer")
val producer = new KafkaProducer[String, String](props)
val TOPIC = "testTopic"
for (i <- 1 to 50) {
val record = new ProducerRecord(TOPIC, "key", s"hello $i")
producer.send(record)
}
val record = new ProducerRecord(TOPIC, "key", "the end" + new java.util.Date)
producer.send(record)
producer.flush()
producer.close()
}
}

I know this is too late, but for others who will be looking for the same issue-
In the latest version of kafka, kafka.utils got deprecated. So please use kafka admin client apis
