Question

Spark Streaming job not reading data from Kafka

Hi, 

 

I am trying to run spark streaming job on cloudera v5.14.4 which will be reading data from kafka v0.10. I am using following version of spark streaming dependencies 

 

spark-streaming_2.11:2.3.0
spark-streaming-kafka-0-10_2.11:2.3.0

 

The job works fine on local but on cloudera it is not starting up. There is no streaming tab on AM and stages/storage tabs are blank.

There are no errors in the logs. Any suggestion what might be wrong here?

Hii somant,

 

there are some information that need to be provided in order to drive the investigation:

  1. From where are you launching the job? E.g. from a gateway of your CDH cluster?
  2. Can you please share your spark-submit command?
  3. You are saying the job is not starting up, do you have any log (Spark driver logs, YARN logs)?

Thanks

Hi @amallegni ,

 

-I am launching the jobs from one of the cluster nodes

-SPARK_KAFKA_VERSION=0.10 spark2-submit --master yarn --deploy-mode cluster --name appName --keytab "****.keytab" --principal "****" --num-executors 3 --driver-memory 4g --executor-memory 3g --executor-cores 3 --files "/path/to/hive-site.xml,/path/to/jaas.conf#jaas.conf" --conf "spark.streaming.unpersist=true" --conf "spark.executor.userClassPathFirst=true" --conf "spark.streaming.kafka.maxRatePerPartition=10" --conf "spark.streaming.kafka.maxRetries=5" --conf "spark.streaming.backpressure.enabled=true" --conf "spark.executor.extraJavaOptions=-XX:+UseG1GC -Djava.security.krb5.conf=/etc/krb5.conf -Djava.security.auth.login.config=./jaas.conf" --conf "spark.driver.extraJavaOptions=-XX:+UseG1GC -Djava.security.krb5.conf=/etc/krb5.conf -Djava.security.auth.login.config=./jaas.conf" --conf spark.yarn.maxAppAttempts=4 --conf spark.yarn.am.attemptFailuresValidityInterval=1h --conf spark.yarn.max.executor.failures=24 --conf spark.yarn.executor.failuresValidityInterval=1h --properties-file /path/to/app.properties

-I am not finding anything in logs. 

 

The only similar issue I found out was this one https://stackoverflow.com/questions/44454520/spark-streaming-is-not-streaming-but-waits-showing-consumer-config-values. I also have a kafka installation version 0.9 and my job needs 0.10 I'm wondering if there is any way that the spark job doesn't depend on the CDH provided libraries and only use packaged dependencies.

Hi @somant ,

 

regarding this " I'm wondering if there is any way that the spark job doesn't depend on the CDH provided libraries and only use packaged dependencies", it depends on the library you are referring to.

If you are referring to kafka libraries, they shouldn't be loaded by spark classpath by default, hence you can prepare a fat jar including the kafka dependencies choosing the version you need.

Moreover, did you try by specifying less options at launch time? 
E.g. I would start by removing the usage of G1GC and other advanced options, monitoring the behaviour one step at a time.

Hi @amallegni 

Thanks for replying. I created a simple word count job and I'm running it using this command 

SPARK_KAFKA_VERSION=0.10 /opt/cloudera/parcels/SPARK2/bin/spark2-submit --num-executors 2 --master local[4] --driver-java-options "-Djava.security.auth.login.config=/apps/raiot/dev/confluent/config/jaas.conf" --class com.cloudera.spark.examples.DirectKafkaWordCount --conf "spark.executor.extraJavaOptions=-Djava.security.auth.login.config=/apps/raiot/dev/confluent/config/jaas.conf" spark-dstream-secure-kafka-app-1.0-SNAPSHOT-jar-with-dependencies.jar

Check the following example code:
