Hi,

Installing Design and Automation nodes in our environment (Linux). Design starts up and portal can be accessed. Automation fails to start with the following error

Win2Nx_0-1607915905112.jpeg

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hadoop/security/UserGroupInformation

Hi,

this error means that the Hadoop integration on this DSS instance is broken (common cause: the Hadoop libs were upgraded on the machine and their location changed). You need to re-run the install-hadoop-integration command
