unable to delete consumeKafka processor on canvas

[#1]

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

[#2]

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.

[#4 · Accepted solution]

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).

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.
