-----------------------------------
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.
