Hi, The error message "Unsupported major.minor version 52.0" means the UDF jar file was compile on a version of Java that is different to the one used for HS2. If you run below command: javap -verbose com/udf/StringSplitter.class | grep "major" What is the number returned? Below are the major version number for different version of Java: Java 5 uses major version 49 Java 6 uses major version 50 Java 7 uses major version 51 Java 8 uses major version 52 Java 9 uses major version 53 So you need to compile using the Java that has the same version that HS2 runs under.
