> Key: NIFI-8282
> URL: https://issues.apache.org/jira/browse/NIFI-8282
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 1.11.4, 1.13.0, 1.12.1
> Environment: Docker Image
> Reporter: Denis Jakupovic
> Assignee: Mark Payne
> Priority: Major
> Labels: CPU, InvokeHTTP, load, primary
> Fix For: 1.14.0, 1.13.1
>
>
> Currently we use over 100 InvokeHTTP processors which are mostly in idle the
> whole time. The InvokeHTTP processors are triggered via an incomming
> connection, so they should do nothing until triggered.
> If set to primary we have a cpu load of 120-150% on 6 cores. When set on all
> nodes the cpu time drops to 20%.
> EDIT: This phenomena occurs if a processor is set to primary if it has an
> incomming connection. Tested on three processors, the CPU on 2 of 3 nodes
> went up to 120-150%.
