spark elasticsearch: Multiple ES-Hadoop versions detected in the classpath

I'm new to spark. I'm trying to run a spark job that loads data to elasticsearch. I've built a fat jar from my code and used it during spark-submit.

spark-submit \
  --class CLASS_NAME \
  --master yarn \
  --deploy-mode cluster \
  --num-executors 20 \
  --executor-cores 5 \
  --executor-memory 32G \
  --jars EXTERNAL_JAR_FILES \
  PATH_TO_FAT_JAR

The maven dependency of elasticsearch-hadoop dependency is:

<dependency>
    <groupId>org.elasticsearch</groupId>
    <artifactId>elasticsearch-hadoop</artifactId>
    <version>5.6.10</version>
    <exclusions>
        <exclusion>
            <groupId>org.slf4j</groupId>
            <artifactId>log4j-over-slf4j</artifactId>
        </exclusion>
    </exclusions>
</dependency>

When I don't include the elasticsearch-hadoop jar file in the EXTERNAL_JAR_FILES list, then I'm getting this error.

java.lang.ExceptionInInitializerError

If I include it in the EXTERNAL_JAR_FILES list, I'm getting this error.

Is there anything that needs to be done to overcome it?

The problem is solved by not including the elasticserach-hadoop jar in the fat jar I've built. I've mentioned scope param to provided in the dependency.

    <dependency>
        <groupId>org.elasticsearch</groupId>
        <artifactId>elasticsearch-hadoop</artifactId>
        <version>5.6.10</version>
        <exclusions>
            <exclusion>
                <groupId>org.slf4j</groupId>
                <artifactId>log4j-over-slf4j</artifactId>
            </exclusion>
        </exclusions>
        <scope>provided</scope>
