> Refactor lifecycle code for Processors and other components
> -----------------------------------------------------------
>
> Key: NIFI-1464
> URL: https://issues.apache.org/jira/browse/NIFI-1464
> Project: Apache NiFi
> Issue Type: Improvement
> Reporter: Oleg Zhurakousky
> Assignee: Oleg Zhurakousky
> Fix For: 0.6.0
>
>
> Similar lifecycle handling improvements that went in as part of the NIFI-1164
> for ControllerServices, could/should be applied to other components (e..g,
> Processors).
> The improvements may also help to address NIFI-78 (may be without killing the
> thread).
