java.lang.NoClassDefFoundError: org/apache/spark/sql/SparkSession

I have written a Spark Job in Java. When I submit the Job it gives below error:

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/spark/sql/SparkSession

Solution

  • when submitting with spark-submit , check that your project has the same dependency as spark version in pom.xml,

    This may be because you have two spark versions on the same machine

    If you want to have different Spark installations on your machine, you can create different soft links and can use the exact spark version on which you have build your project

    spark1-submit -> /Users/test/sparks/spark-1.6.2-bin-hadoop2.6/bin/spark-submit

spark2–submit -> /Users/test/sparks/spark-2.1.1-bin-hadoop2.7/bin/spark-submit

    Here is a link from Cloudera blog about multiple Spark versions https://community.cloudera.com/t5/Advanced-Analytics-Apache-Spark/Multiple-Spark-version-on-the-same-cluster/td-p/39880
