Dheeraj Joshi commented on NIFI-11322: -------------------------------------- https://issues.apache.org/jira/browse/NIFI-12232 > ClusterSynchronization errors > ----------------------------- > > Key: NIFI-11322 > URL: https://issues.apache.org/jira/browse/NIFI-11322 > Project: Apache NiFi > Issue Type: Bug > Components: Core Framework > Affects Versions: 1.19.1 > Reporter: Phil Lord > Priority: Major > Attachments: App.log events.txt, StackTraceFromUser.log > > > Environment: Small 3-node cluster; 4GB Heap/4 Cores per node > See attachments referencing errors in both user.log and corresponding > app.log. I'm not sure if these errors might be resolved in some of the > tickets being addressed in 1.21.0? The only resolution was a restart of the > node... attempts to re-sync the node through a UI level connection request > failed. Of note the errors were seen within a Registry versioned > ProcessGroup. > 2023-03-21 02:43:16,574 INFO [Reconnect to Cluster] > o.a.nifi.controller.StandardFlowService Node disconnected due to Failed to > properly handle Reconnection request due to > org.apache.nifi.controller.serialization.FlowSynchronizationException: Failed > to connect node to cluster because local flow controller partially updated. > Administrator should disconnect node and review flow for corruption. > 2023-03-21 02:43:16,574 ERROR [Reconnect to Cluster] > o.a.nifi.controller.StandardFlowService Handling reconnection request failed > due to: > org.apache.nifi.controller.serialization.FlowSynchronizationException: Failed > to connect node to cluster because local flow controller partially updated. > Administrator should disconnect node and review flow for corruption. > org.apache.nifi.controller.serialization.FlowSynchronizationException: Failed > to connect node to cluster because local flow controller partially updated. > Administrator should disconnect node and review flow for corruption. > at > org.apache.nifi.controller.StandardFlowService.loadFromConnectionResponse(StandardFlowService.java:1059) > at > org.apache.nifi.controller.StandardFlowService.handleReconnectionRequest(StandardFlowService.java:667) > at > org.apache.nifi.controller.StandardFlowService.access$200(StandardFlowService.java:107) > at > org.apache.nifi.controller.StandardFlowService$1.run(StandardFlowService.java:396) > at java.base/java.lang.Thread.run(Thread.java:829) > Caused by: > org.apache.nifi.controller.serialization.FlowSynchronizationException: > java.lang.IllegalStateException: Upstream component of Connection > (PutS3Object[id=9fcf34ef-d59e-16bc-9e3c-7c619c5e40af]) is running > at > org.apache.nifi.controller.serialization.VersionedFlowSynchronizer.synchronizeFlow(VersionedFlowSynchronizer.java:447) > at > org.apache.nifi.controller.serialization.VersionedFlowSynchronizer.sync(VersionedFlowSynchronizer.java:205) > at > org.apache.nifi.controller.serialization.StandardFlowSynchronizer.sync(StandardFlowSynchronizer.java:42) > at > org.apache.nifi.controller.FlowController.synchronize(FlowController.java:1525) > at > org.apache.nifi.persistence.StandardFlowConfigurationDAO.load(StandardFlowConfigurationDAO.java:104) > at > org.apache.nifi.controller.StandardFlowService.loadFromBytes(StandardFlowService.java:817) > at > org.apache.nifi.controller.StandardFlowService.loadFromConnectionResponse(StandardFlowService.java:1028) > ... 4 common frames omitted > Caused by: java.lang.IllegalStateException: Upstream component of Connection > (PutS3Object[id=9fcf34ef-d59e-16bc-9e3c-7c619c5e40af]) is running > at > org.apache.nifi.connectable.StandardConnection.verifySourceStoppedOrFunnel(StandardConnection.java:529) > at > org.apache.nifi.connectable.StandardConnection.verifyCanDelete(StandardConnection.java:510) > at > org.apache.nifi.groups.StandardProcessGroup.removeConnection(StandardProcessGroup.java:1375) > at > org.apache.nifi.flow.synchronization.StandardVersionedComponentSynchronizer.removeMissingConnections(StandardVersionedComponentSynchronizer.java:619) > at > org.apache.nifi.flow.synchronization.StandardVersionedComponentSynchronizer.synchronize(StandardVersionedComponentSynchronizer.java:383) > at > org.apache.nifi.flow.synchronization.StandardVersionedComponentSynchronizer.synchronizeChildGroups(StandardVersionedComponentSynchronizer.java:537) > at > org.apache.nifi.flow.synchronization.StandardVersionedComponentSynchronizer.synchronize(StandardVersionedComponentSynchronizer.java:411) > at > org.apache.nifi.flow.synchronization.StandardVersionedComponentSynchronizer.lambda$synchronize$0(StandardVersionedComponentSynchronizer.java:255) > at > org.apache.nifi.controller.flow.AbstractFlowManager.withParameterContextResolution(AbstractFlowManager.java:550) > at > org.apache.nifi.flow.synchronization.StandardVersionedComponentSynchronizer.synchronize(StandardVersionedComponentSynchronizer.java:253) > at > org.apache.nifi.groups.StandardProcessGroup.synchronizeFlow(StandardProcessGroup.java:3970) > at > org.apache.nifi.controller.serialization.VersionedFlowSynchronizer.synchronizeFlow(VersionedFlowSynchronizer.java:438) > ... 10 common frames omitted -- This message was sent by Atlassian Jira (v8.20.10#820010)
