I have NiFi 1.2.0 installed on the Windows 2012 R2 server, it creates the standard logs files as under: nifi-bootstrap.log nifi-app.log nifi-user.log Issue is that these files are not rolling over daily or based on size. Can someone help? I have attached the logback.xml file. Also, are the changes to this logback.xml dynamically implemented, or it requires NiFi to get into effect? ... View more

I have built a custom controller service and custom processor. I am able to build and run tests in IntelliJ on my laptop. Once the maven build is successfully complete, I copied all the 3 nar files and dropped them in the lib folder of NiFi. In NiFi web interface, I can the see my custom service in Controller Service page. I am able to configure it and enable it. NiFi logs confirms the service is online. Now, when I drop the custom processor, I cannot see the service to choose in drop down. Event though it is service is running. I verified the dependencies in pom for all nar modules. nifi-customservice-api-nar nifi-customservice-nar nifi-LookupProcessor-nar Following is the error in the NiFi app log: java.lang.IllegalArgumentException: ControllerServices may be referenced only via their interfaces; class org.pwc.nifi.customservice.LookupService is not an interface at org.apache.nifi.attribute.expression.language.StandardPropertyValue.asControllerService(StandardPropertyValue.java:172) ~[nifi-expression-language-1.1.1.jar:1.1.1] at org.pwc.nifi.customservice.LookupProcessor.onTrigger(LookupProcessor.java:79) ~[na:na] at org.apache.nifi.processor.AbstractProcessor.onTrigger(AbstractProcessor.java:27) ~[nifi-api-1.1.1.jar:1.1.1] at org.apache.nifi.controller.StandardProcessorNode.onTrigger(StandardProcessorNode.java:1099) ~[nifi-framework-core-1.1.1.jar:1.1.1] at org.apache.nifi.controller.tasks.ContinuallyRunProcessorTask.call(ContinuallyRunProcessorTask.java:136) [nifi-framework-core-1.1.1.jar:1.1.1] at org.apache.nifi.controller.tasks.ContinuallyRunProcessorTask.call(ContinuallyRunProcessorTask.java:47) [nifi-framework-core-1.1.1.jar:1.1.1] at org.apache.nifi.controller.scheduling.TimerDrivenSchedulingAgent$1.run(TimerDrivenSchedulingAgent.java:132) [nifi-framework-core-1.1.1.jar:1.1.1] at java.util.concurrent.Executors$RunnableAdapter.call(Unknown Source) [na:1.8.0_91] at java.util.concurrent.FutureTask.runAndReset(Unknown Source) [na:1.8.0_91] at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$301(Unknown Source) [na:1.8.0_91] at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(Unknown Source) [na:1.8.0_91] at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) [na:1.8.0_91] at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) [na:1.8.0_91] at java.lang.Thread.run(Unknown Source) [na:1.8.0_91] I would appreciate if someone can help with : Resolving missing service in drop down when configuring the processor in properties.
