Hi, Unfortunately it is built with java 11 and will not work on Java 8 so. However, you can install Java 11 on only one node, along with Java 8 and let Java 8 be the default (so you do not impact any of CDP components or your programs). Then go in CM > Datagen > Configuration and set java_home_custom to the path on the node where Java 11 is installed. Datagen should start with it. Thanks. ... View more
