Spark-submit to deploy the jar to Spark - java.lang.ClassNotFoundException

Explorer

Hi, I'm doing the following tutoria.

https://es.hortonworks.com/tutorial/deploying-machine-learning-models-using-spark-structured-streami...

I'm using the HDP version is HDP-2.5.0.0-1245, the spark version is 1.6.2 and the scala version is 2.10.5.

I have reached this point of the tutorial: Then use spark-submit to deploy the jar to Spark.

I am trying to submit a job which is in target/main/scala, which is a jar file, with the following lines:

/usr/hdp/current/spark2-client/bin/spark-submit --class "main.scala.Collect" --master local[4] ./SentimentAnalysis-assembly-2.0.0.jar

All goes well, except the following errors:

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

Re: Spark-submit to deploy the jar to Spark - java.lang.ClassNotFoundException

@David Sandoval The code from the link you shared is using Spark 2 and is streaming from Kafka using Structured Streaming. Structured Streaming is TP since HDP 2.6.3. You are running HDP 2.5 with spark 1.6, you should try following link steps using 2.6.3 onwards with spark 2.
