Hi, Depends on how exactly you start the SharedRDDExample?
1)In case if you use the new maven project then possible you forgot to add dependencies for Ignite spark: <dependency> <groupId>org.apache.ignite</groupId> <artifactId>ignite-core</artifactId> <version>2.7.0</version> </dependency> <dependency> <groupId>org.apache.ignite</groupId> <artifactId>ignite-spring</artifactId> <version>2.7.0</version> </dependency> <dependency> <groupId>org.apache.ignite</groupId> <artifactId>ignite-indexing</artifactId> <version>2.7.0</version> </dependency> <dependency> <groupId>org.apache.ignite</groupId> <artifactId>ignite-spark</artifactId> <version>2.7.0</version> </dependency> 2)In case if you are going to build from the source then check that you set the IGNITE_HOME. If everything fine then provide the full build log error. BR, Andrei -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
