> 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.
