Pradeep, This means the NiFi you are accessing the UI from is trying to replicate a request to another NiFi in the cluster running on sabc.abcd.local:9090 and couldn't complete the replication due to a read timeout.
Can you verify there is a NiFi running at sabc.abcd.local:9090? Can you access the UI of the other NiFi at http://sabc.abcd.local:9090/nifi ? -Bryan On Tue, May 2, 2017 at 12:14 PM, pradeepbill <pradeep.b...@gmail.com> wrote: > hello folks, I see this exception, and can not open the NIFI console.There is > connectivity between the nodes in the cluster on port 9090.Any clues would > help. > > 2017-05-02 11:50:18,607 WARN [Replicate Request Thread-2] > o.a.n.c.c.h.r.ThreadPoolRequestReplicator Failed to replicate request GET > /nifi-api/flow/process-groups/root to sabc.abcd.local:9090 due to {} > com.sun.jersey.api.client.ClientHandlerException: > java.net.SocketTimeoutException: Read timed out > at > com.sun.jersey.client.urlconnection.URLConnectionClientHandler.handle(URLConnectionClientHandler.java:155) > ~[jersey-client-1.19.jar:1.19] > at com.sun.jersey.api.client.Client.handle(Client.java:652) > ~[jersey-client-1.19.jar:1.19] > at > com.sun.jersey.api.client.filter.GZIPContentEncodingFilter.handle(GZIPContentEncodingFilter.java:123) > ~[jersey-client-1.19.jar:1.19] > at > com.sun.jersey.api.client.WebResource.handle(WebResource.java:682) > ~[jersey-client-1.19.jar:1.19] > at > com.sun.jersey.api.client.WebResource.access$200(WebResource.java:74) > ~[jersey-client-1.19.jar:1.19] > at > com.sun.jersey.api.client.WebResource$Builder.get(WebResource.java:509) > ~[jersey-client-1.19.jar:1.19] > at > org.apache.nifi.cluster.coordination.http.replication.ThreadPoolRequestReplicator.replicateRequest(ThreadPoolRequestReplicator.java:578) > ~[nifi-framework-cluster-1.0.0.2.0.1.0-12.jar:1.0.0.2.0.1.0-12] > at > org.apache.nifi.cluster.coordination.http.replication.ThreadPoolRequestReplicator$NodeHttpRequest.run(ThreadPoolRequestReplicator.java:770) > ~[nifi-framework-cluster-1.0.0.2.0.1.0-12.jar:1.0.0.2.0.1.0-12] > at > java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) > [na:1.8.0_111] > at java.util.concurrent.FutureTask.run(FutureTask.java:266) > [na:1.8.0_111] > at > java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) > [na:1.8.0_111] > at > java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) > [na:1.8.0_111] > at java.lang.Thread.run(Thread.java:745) [na:1.8.0_111] > Caused by: java.net.SocketTimeoutException: Read timed out > > thanks > Pradeep > > > > -- > View this message in context: > http://apache-nifi-developer-list.39713.n7.nabble.com/failed-to-replicate-request-GET-NIFI-API-flow-process-groups-root-to-saxx-9090-tp15612.html > Sent from the Apache NiFi Developer List mailing list archive at Nabble.com.
