While setting partitionSize=0 so as to fetch all the rows in the given table for GenerateTableFetch Processor in Nifi, I am getting the following error:
ERROR [Timer-Driven Process Thread-4] o.a.n.p.standard.GenerateTableFetch GenerateTableFetch[id=d0932834-015d-1000-8224-c230630b6fa6] GenerateTableFetch[id=d0932834-015d-1000-8224-c230630b6fa6] failed to process session due to java.lang.NullPointerException: {} java.lang.NullPointerException: null at org.apache.nifi.processors.standard.GenerateTableFetch.onTrigger(GenerateTableFetch.java:300) at org.apache.nifi.controller.StandardProcessorNode.onTrigger(StandardProcessorNode.java:1120) at org.apache.nifi.controller.tasks.ContinuallyRunProcessorTask.call(ContinuallyRunProcessorTask.java:147) at org.apache.nifi.controller.tasks.ContinuallyRunProcessorTask.call(ContinuallyRunProcessorTask.java:47) at org.apache.nifi.controller.scheduling.TimerDrivenSchedulingAgent$1.run(TimerDrivenSchedulingAgent.java:132) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.runAndReset(FutureTask.java:308) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$301(ScheduledThreadPoolExecutor.java:180) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:294) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:748)
When I give partitionSize>0 it works. How can I resolve this error?
