Setting deployment synchronizer for WSO2 Identity Server 5.1.0 worker node

问题

I am trying to setup WSO2 Identity Server 5.1.0 cluster using the Manager/Worker deployment pattern following this guide.

I managed to set up successfully the deployment synchronizer for the manager node. However when I start the worker node using the option "-DworkerNode=true", I get the following error:

If I started the same node with "-DworkerNode=false" no error happens.

WSO2 IS 5.1.0 doesn't need the worker/manager separation. For further details read [1] and [2].

Thanks.
