----------------------------------

             Summary: Inflight events in file channel should not be using MD5 
for integrity purposes
                 Key: FLUME-3406
                 URL: https://issues.apache.org/jira/browse/FLUME-3406
             Project: Flume
          Issue Type: Improvement
          Components: File Channel
            Reporter: Matt Sicker


FlumeEventQueue's inner class InflightEventWrapper uses MD5 for calculating a 
digest of inflight events. MD5 has been considered unsuitable for cryptographic 
usage such as for integrity checks for many years now. This should migrate to 
SHA-256 at least.
