> I am trying to Bulk Load data from HDFS to HBase. I used the following example [https://github.com/apache/hbase-connectors/blob/master/spark/hbase-spark/src/main/java/org/apache/hadoop/hbase/spark/example/hbasecontext/JavaHBaseBulkLoadExample.java] 
> I built the module with following command 
> mvn -Dspark.version=2.4.3 -Dscala.version=2.11.7 -Dscala.binary.version=2.11 clean install
> when i tried to run the example using the spark-submit command, i am getting the following error:
