> Cluster stability issues during high throughput
> -----------------------------------------------
>
> Key: NIFI-3257
> URL: https://issues.apache.org/jira/browse/NIFI-3257
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 1.0.0, 1.1.0, 1.1.1, 1.0.1
> Reporter: Jeff Storck
>
> During high throughput of data in a cluster (135MB/s), nodes experience
> frequent disconnects (every few minutes) and role switching (Primary and
> Cluster Coordinator). This makes API requests difficult since the requests
> can not be replicated to all nodes while reconnecting. The cluster can
> recover for a time (as mentioned above, for a few minutes) before going
> through another round of disconnects and role switching.
> The cluster is able to continue to process data during these connection and
> role-switching issues.
