Not able to load NIFI process

Aiiyer — Mon, 26 Jul 2021 21:57:43 GMT

I am trying to load a process template in NIFI but it gives below error: org.apache.nifi.processors.kafka.pubsub.ConsumeKafka_0_10.
Below is the log from nifi-app.log file:

I also increased the memory from 512m to 4G in the bootstrap.config file by updating

java.arg.3=-XmX4G

Could anyone please help me resolve this. Thanks in advance!

@Aiiyer

What ERROR? All I see are a bunch of normal INFO log lines form the nifi-app.log snippet you shared.

Please share the ERROR log line and stack trace if present.
Or share screenshots of what you are doing and observing.

Thank you,
Matt
