> As reported on the mailing list, when NiFi is running in unsecured mode (HTTP), a request can be intercepted (or simply be a malicious request from origin) and have a large request header injected, which can result in Jetty throwing an {{OutOfMemoryError}}. 
> This was reported with reference to the {{NCM}}, which indicates a {{0.x}} release. Normal HTTP requests to the API will fail with HTTP response {{413}} - {{Request Entity Too Large}}. Further investigation is needed as this may only be related to cluster operations. 
> The {{setRequestHeaderSize}} method [1] should allow for prevention of this issue.
