Improving the NiFi security model

All, As I have been working around restricting the level of filesystem privileges required by NiFi to run, I started to wonder how to tackle what in my opinion is one of the biggest challenges around NiFi: How to ensure the ExecuteProcessors, FS processors (GetFile/PutFile) aren't misused by a

Re: Processor running slow in production, not locally

Russ, As Jeff points out lack of available threads could be a factor flow slower processing times but this would manifest itself by you seeing that the processor isn't running very often. If it is that the process itself when executing takes much longer than on the other box then it is probably

ExecuteProcess fails to identify environment variable in the script

I am trying to run a remote script through a script in my host environment from the ExecuteProcess processor in NiFi. Basically, the shell script in the host server has the ssh string to the remote server and calling the script in that remote server. I used sshpass package where I saved the

Re: Problem compiling

I compile trough Maven on intellij 2016 but the problem comes from antlr v3. A language parser that is not understood natively by the compiler. I tried the antlworks plugin but It still didn't. I'll try tomorow read the doc to configure it properly Le 3 oct. 2016 17:22, "Mark Payne"

Re: Processor running slow in production, not locally

Russel, This sounds like it's an environmental issue. Are you able to see the heap usage on the production machine? Are there enough available threads to get the throughput you are observing when you run locally? Have you double-checked the scheduling tab on the processor config to make sure

Re: Problem compiling

Mathias, How are you trying to compile it? If using Maven, it should work just fine. If you are using an IDE such as Eclipse you may need to first compile via Maven to get the generated code and then add those directories as source directories. Thanks -Mark > On Oct 3, 2016, at 10:33 AM,

I am reviewing the PR for NIFI-2774 ConsumeJMS and we need someone to review the PR for NIFI-2429 PersistentProvenanceRepository. Once those are complete I think we can start the process to cut 0.7.1. -- Mike On Mon, Oct 3, 2016 at 9:49 AM, Tony Kurc wrote: > So, sounds like

So, sounds like we have enough support to go ahead. How are we feeling about what our timeline should be on this? On Wed, Sep 28, 2016 at 11:14 PM, Joe Witt wrote: > +1 to an 0.7.1 with the bugs that have been addressed already. > Even bigger +1 to Tony volunteering as RM!

Processor running slow in production, not locally

We use NiFi for an ETL feed. On one of the lines, we use a custom processor, *VelocityTemplating* (calls Apache Velocity), which work very well and indeed is imperceptibly fast when run locally on the same data (template, VTL macros, substitution fodder). However, in production it's another
