[jira] [Created] (NIFI-2268) HandleHttpRequest can use too many tasks and CPU

Michael Moser created NIFI-2268:
-----------------------------------

             Summary: HandleHttpRequest can use too many tasks and CPU
                 Key: NIFI-2268
                 URL: https://issues.apache.org/jira/browse/NIFI-2268
             Project: Apache NiFi
          Issue Type: Bug
          Components: Extensions
    Affects Versions: 0.7.0
            Reporter: Michael Moser
            Priority: Minor


With the default settings of HandleHttpRequest, user reports 100% CPU usage and millions of scheduled tasks.  When this processor doesn't have work to do, its onTrigger() should call ProcessContext.yield().  This is how the ListenHTTP processor works, so it's an established pattern.
