What's New in RapidMiner Server 8.1.1?

Released: April 10th, 2018

The following describes the enhancements and bug fixes in RapidMiner Server 8.1.1:

New Features

  • Added two new execution properties for timeout checks:
    • jobservice.scheduled.agentTimeoutAfter: If a Job Agent does not send a heartbeat the Job Agent is flagged as timed-out after this period in milliseconds (default: 30000)
    • jobservice.scheduled.jobTimeoutAfter: Jobs are flagged as timed-out after this period in milliseconds if no update/heartbeat for the job was received (default: 30000)


  • Processes which contain dummy / unknown operators will now fail fast and will not be submitted to Job Agents
  • Processes which are executed by Job Agents will ignore breakpoints
  • Improved error message when remote Job Agent cannot connect to RapidMiner Server
  • Improved token renewal schedule for Job Container authorization
  • Job Container will no longer fail instantly if RapidMiner Server is temporarily unavailable during Job start. Instead, it will try to re-establish the connection up to five times
  • In the Job Agent, separated the bundled extensions folder from the custom extensions folder by moving it to engine/plugins


  • Fixed problem with PostgresSQL which led to the execution details page not being displayed
  • Fixed RapidMiner Server installer failure for Oracle DB
  • Fixed a problem with Trigger permission handling which allowed users without execute permission to run processes
