> GetTCP does not reestablish connection
> --------------------------------------
>
> Key: NIFI-5959
> URL: https://issues.apache.org/jira/browse/NIFI-5959
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 1.8.0, 1.7.1
> Environment: Ubuntu 18.4
> Reporter: Craig Knell
> Priority: Major
> Labels: GetTCP
>
> GetTCP does not reconnect when connection is broken.
> Netstat reveals that the connection remains ESTABLISHED.
> I understand that as GetTCP does not issue a heartbeat, GetTCP has no way on
> knowing that the connection has failed; as TCP does not know that the
> connection has failed. It is still ESTABLISHED.
> Workaround:
> Manually restating GetTCP processor when remote site is up fixes the
> connection.
> Netstat reveals that FIN_WAIT1, then ESTABLISHED occurs, as expected.
