Hi I am trying out the Wait\Notify Processors in Nifi 1.2 for the
first time. In the Property for Distributed
Cache Service I choose create new service. Under Properties of that service I just pick the hostname of
the localserver where nifi is running as
Server Hostname and all lights changed on go. But when i started the Prozessors I got this error messege: 2017-07-12 14:28:09,563 ERROR [Timer-Driven Process Thread-6] org.apache.nifi.processors.standard.Wait Wait[id=115238a2-299b-1267-98b6-14d1a4eb45e8] Failed to process session due to org.apache.nifi.processor.exception.ProcessException: Failed to get signal for TOC_2017cw14_WGS84_umts due to java.net.ConnectException: Connection refused: {}
