Hi, I am trying to submit a job to spark to count number of words in a specific kafka topic but I get below exception when I check the log:
..... failed with unrecoverable exception: java.lang.NullPointerException The command that I run follows: ./scripts/dm-spark-submit.sh --class org.apache.spark.examples.streaming.DirectKafkaWordCount zookeeper:2181 my-topic --executor-memory 1G --total-executor-cores 2 /spark-apps/spark-examples-SNAPSHOT.jar Please note that my spark, kafka, zookeeper are running in different containers named, spark,kafka,zookeeper. I tried the wordCount in java streaming as well, same error exists! Any idea about cause of the error? Kindest regards, Mina
