For example, I ran across 1 node cluster configured > with a remote input hostname that started with a "http:// ...". This cluster > started up and everything seemed fine on it's end but on the client side it > failed. > After the initial connection it received "http:// ..." as the hostname for it > to connect to causing UnknownHostExceptions. > NiFi should validate that the value set for the remote input host is valid in > order to avoid this issue. > Example: > 2016-10-25 11:18:29,132 ERROR [Timer-Driven Process Thread-6] > o.a.nifi.remote.StandardRemoteGroupPort RemoteGroupPort[name=From > MiNiFi,target=http://<HOSTNAME>:9090/nifi/] failed to communicate with > http://<HOSTNAME>:9090/nifi/ due to java.net.UnknownHostException > 2016-10-25 11:18:29,136 ERROR [Timer-Driven Process Thread-6] > o.a.nifi.remote.StandardRemoteGroupPort > java.net.UnknownHostException: null > at sun.nio.ch.Net.translateException(Net.java:155) ~[na:1.8.0_74] > at sun.nio.ch.SocketAdaptor.connect(SocketAdaptor.java:127) ~[na:1.8.0_74] > at > org.apache.nifi.remote.client.socket.EndpointConnectionPool.establishSiteToSiteConnection(EndpointConnectionPool.java:712) > ~[nifi-site-to-site-client-0.6.1.jar:0.6.1] > at > org.apache.nifi.remote.client.socket.EndpointConnectionPool.establishSiteToSiteConnection(EndpointConnectionPool.java:685) > ~[nifi-site-to-site-client-0.6.1.jar:0.6.1] > at > org.apache.nifi.remote.client.socket.EndpointConnectionPool.getEndpointConnection(EndpointConnectionPool.java:301) > ~[nifi-site-to-site-client-0.6.1.jar:0.6.1] > at > org.apache.nifi.remote.client.socket.SocketClient.createTransaction(SocketClient.java:129) > ~[nifi-site-to-site-client-0.6.1.jar:0.6.1] > at > org.apache.nifi.remote.StandardRemoteGroupPort.onTrigger(StandardRemoteGroupPort.java:171) > ~[nifi-site-to-site-0.6.1.jar:0.6.1] > at org.apache.nifi.controller.AbstractPort.onTrigger(AbstractPort.java:227) > [nifi-framework-core-api-0.6.1.jar:0.6.1] > at > org.apache.nifi.controller.tasks.ContinuallyRunConnectableTask.call(ContinuallyRunConnectableTask.java:81) > [nifi-framework-core-0.6.1.jar:0.6.1] > at > org.apache.nifi.controller.tasks.ContinuallyRunConnectableTask.call(ContinuallyRunConnectableTask.java:40) > [nifi-framework-core-0.6.1.jar:0.6.1] > at > org.apache.nifi.controller.scheduling.TimerDrivenSchedulingAgent$1.run(TimerDrivenSchedulingAgent.java:123) > [nifi-framework-core-0.6.1.jar:0.6.1] > at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) > [na:1.8.0_74] > at java.util.concurrent.FutureTask.runAndReset(FutureTask.java:308) > [na:1.8.0_74] > at > java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$301(ScheduledThreadPoolExecutor.java:180) > [na:1.8.0_74] > at > java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:294) > [na:1.8.0_74] > at > java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) > [na:1.8.0_74] > at > java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) > [na:1.8.0_74] > at java.lang.Thread.run(Thread.java:745) [na:1.8.0_74] -- This message was sent by Atlassian JIRA (v6.3.4#6332)
