             Summary: 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: 1.0.1, 1.1.1, 1.1.0, 1.0.0
            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.
