             Summary: Node shouldn't be disconnected from a cluster when clear component state operation gets error related to underlying data source
                 Key: NIFI-2364
                 URL: https://issues.apache.org/jira/browse/NIFI-2364
             Project: Apache NiFi
          Issue Type: Bug
          Components: Core Framework
    Affects Versions: 1.0.0
            Reporter: Koji Kawamura
            Assignee: Koji Kawamura
             Fix For: 1.0.0


NodeClusterCoordinator.afterRequest() disconnects a node if it couldn't handle mutation requests such as POST, assuming that node is not functioning properly.

However, if the cause of issue is related to an external data source, such as Zookeeper or Kafka, other node will have the same problem even if other node is elected as a primary node. In such case, disconnecting node wouldn't be a good recovery solution. Instead, the node should keep connected, and let users retry the operation.
