Greetings, I’d like to describe some observations we are witnessing and to see if anyone has seen this before or has any thoughts on the matter. Any helpful advice would be appreciated. I am remotely trying to help some folks on a system that has just been upgraded from nifi 0.6.x to 1.3.x. They are simply running nifi via the “nifi.sh start” technique now and not as a service and have nuked their nifi repos to help avoid issues when upgrading. On our development baseline we’ve done the upgrade smoothly to nifi 1.3.0 months ago and have never seen what is being described. Thus, a nifi flow is being used that has already been updated months ago for nifi 1.3.0 and thus is already complaint. I’ve also ensured our custom nars are in the nifi-lib dir, etc. And, those custom nars were also upgraded months ago to use 1.3.0 compliant nifi processor related classes.
The observations occurring in NiFi UI: 1) the nifi processors are coming up unlabeled and their outlines are skeleton-dotted-lines. 2) all connections to each processor are each red dotted lines 3) in the top left menu of the nifi where all the icons are for adding processors, input ports, etc., when a mouseover occurs, instead of seeing a hand, we see a the equivalent of a “do NOT symbol”. (i.e. the symbol in the do not smoking sign) I’ve had someone lightly look at the logs for anything special, especially the word “validation” in case there were any bizarre XML validation errors on the nifi flow file. Again, any thoughts or advice would be appreciated. Thanks. Regards, -- Jeremy H. Taylor Software Developer ACES, Incorporated http://acesinc.net<http://acesinc.net/>
