HiveMQ AWS cluster not starting

When trying to set up a HiveMQ (1.4.1) Cluster on AWS (using the bundles examples/cluster.xml file) the server upstart fails with an error:

Unable to load class for protocol pbcast.STREAMING_STATE_TRANSFER

There's really no more info on why this would fail.

Solution

  • The problem was that the examples/cluster.xml file used the old syntax for STREAMING_STATE_TRANSFER, while it should use just STATE_TRANSFER instead.

    Hope that helps someone else. :)
