Re evaluate this on both 0.8.3.3 and Master and find out where the issues is.
Something that might help
The fix for this in 0.8.3 was in this git commit, where the feed schedule was doing a save passing in all the properties (which included the *** for the sensitive values) at that time, removing the properties during the save on the schedule fixed the issue:
Cannot reproduce on master. Will try 0.8.3.3
The issue is back on 0.8.3.3. The patch for 0.8.3.3 is available here: https://s3-us-west-2.amazonaws.com/thinkbig.kylo/KYLO-865/kylo-nifi-rest-client-api-0.8.3.3.jar
Committed the fix to 0.8.3.4-SNAPSHOT
Could not reproduce this yesterday on master, but today i did. Very strange. Would have bet money yesterday that issue does not occur on master....
Committed the fix to master too.
