Unable to update processor...

I have a custom processor that I have updated (in potentially breaking ways and I know it), but I cannot seem to make NiFi 1.10.0 open its mouth and swallow it. I have copied my NAR file to /1.10.0/custom-lib/; there is no other version (in the /lib/ subdirectory for example). When I bounce

NiFi 1.10.0 JRE clarification...

Looking at the release notes, I see: * Apache NiFi can now be built on either Java 8 or Java 11! When built on Java 8 it can run on Java 8 or Java 11. The implications of this statement make me ask: * At https://nifi.apache.org/download.html, how is it built? JDK 11? * Can I run it using

Re: [DISCUSS] Time based release cycles

Kafka is first-rate, rock-star technology, just as is NiFi. It would be nice to find something from Kafka elaborating on how this regular and accelerated release cadence is working out for them, how much more work it's been, what problems they've experienced, etc. I show their releases over

Re: Azure Event Hub Processors Upgrade Problem

I can probably help, Sunny. I made some notes a few years ago on doing this. How this is done on later versions hasn't changed I don't think. Check out http://www.javahotchocolate.com/notes/nifi.html#20160323. Russ Bateman On 8/22/19 11:12 AM, Sunny Zhang wrote: Hi there, I’m a dev from

Yes, at the risk of adding nothing more than a "me too," I nevertheless wish to add my thanks. Good job! On 8/15/19 12:04 PM, Jeff wrote: Apache NiFi Developers, Apache NiFi can now be built with Java 11! Thanks to those that helped with the review and committing of several PRs to get us to

StateManager race condition potential

I'm assuming that the StateManagerprotects itself against race conditions for the consuming (custom) processor, but I'd like confirmation on that. Let's say something simple like we get an integer out of state to which we can add one to get the next (piece of work to do), then immediately bump

Re: [board report] Apache NiFi - July 2019

I mulled over whether it's appropriate to ask within this context. I guess I'll ask. Slap me if I have badly chosen, but where is NiFi respective to "modern" JDK versions? Is that too much detail for the audience of this periodic report? Thanks. On 7/10/19 11:15 AM, Joe Witt wrote: Team, I

Re: nifi

It's short for "Niagra files" in the sense that you're meant to think of huge flows of files like water over the falls . On 7/5/19 6:00 AM, Arpad Boda wrote: "nye fye" (nī fī) is the preferred pronunciation. https://nifi.apache.org/faq.html On

NAR extensions warning during build

In /pom.xml/, I have:   *org.apache.nifi*   *nifi-nar-maven-plugin*   *3.5.1*   *true* I get this, which isn't fatal, when my NAR is built. I would like a) to know to what "extension(s)" this refers (related to the plug-in configuration in /pom.xml/?), b) where to put extension

Latest NiFi customs?

After a couple of years absence from NiFi (prior to Java 9), I find myself just now back in a developer role in a company that uses NiFi. (This is a pleasant thought, I might add, as I believe that NiFi rocks.) I have inherited an existing implementation that's sorely aged and, though I've
