Subject Re: UI is not opening after forming nifi 1.0.0 secure cluster in windows
Date Fri, 11 Nov 2016 06:54:04 GMT

Thanks for your response,error I received in browser has been attached

I have generated the key store and truststore file using the java keytool,
Is it necessary to generate the key file in open ssl ?

In nifi-app.log everything seems right,except this warning message

org.apache.nifi.cluster.protocol.ProtocolException: Failed marshalling
protocol message in response to message type: CONNECTION_REQUEST due to Software caused connection abort: socket write
at [na:1.8.0_91]
