I am trying to configure the 3node secured Nifi cluster setup by followinng the below Link <https://pierrevillard.com/2016/11/29/apache-nifi-1-1-0-secured-cluster-setup/> .
But between nodes the connection not happened after enabled SSL/LDAP and i am getting the below error. 2017-04-01 09:05:47,494 WARN [Clustering Tasks Thread-2] o.apache.nifi.controller.FlowController Failed to send heartbeat due to: org.apache.nifi.cluster.protocol.ProtocolException: Failed marshalling 'HEARTBEAT' protocol message due to: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target 2017-04-01 09:05:47,494 ERROR [Process Cluster Protocol Request-7] o.a.nifi.security.util.CertificateUtils The incoming request did not contain client certificates and thus the DN cannot be extracted.
