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

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
