This manual is for an old version of Hazelcast Jet, use the latest stable version.

You may see the following exceptions thrown when working with Jet:

  • JetException: A general exception that will be thrown if a job failure occurs. It will have the original exception in the cause field.
  • TopologyChangedException: This exception is thrown when a member participating in a job leaves the cluster. The job will typically be restarted automatically without throwing the exception to the user if auto-restart is enabled.
  • JobNotFoundException: Thrown when the coordinator node is not able to find the metadata for a given job.

Furthermore, there are several Hazelcast exceptions that might be thrown when interacting with JetInstance. For description of Hazelcast IMDG exceptions, please refer to the IMDG Reference manual.
