unable to delete consumeKafka processor on canvas

Explorer

Please check attachment i''m not able to delete the consumeKafka processor. i also wanted to know what does the small icon on right-upper corner of processor with some number mean. i guessing this must show some kind of warning messages but nothing happens on mouse hover.nifi-processor-error.png

The icon/number in the right-upper corner is the number of tasks the processor is executing. More information about these "active tasks" can be found in the documentation (https://nifi.apache.org/docs/nifi-docs/html/user-guide.html#processor_anatomy).

Which Kafka version are you using? The timeout handling varied greatly between 0.8, 0.9 and 0.10, Match the consumer processor to the broker version, please (0.8 -> Put/Get/Kafka, 0.9 -> Publish/Consume, 0.10 -> Publish/Consume_0_10).

You might be running into this issue: https://issues.apache.org/jira/browse/NIFI-2739

If you can't wait until NiFi 1.1 is released, this patch is already included in HDF 2.0

The number in the top-right corner of the processor is showing how many active threads there are executing for this component.

Sometimes you have to delete the connection between two processors before you can delete one of the processors. Try that to see if you can delete your processor.

i tried deleting the connection flow, it didn't work as well. later i restarted NIFI and processor came out of indefinite block state.
