Guozhang Wang commented on KAFKA-3887:
--------------------------------------
Did some investigation on
https://jenkins.confluent.io/job/system-test-kafka/275/consoleFull.
It turns out to be depending on a timing issue, where the `echo` topic has been
consumed completely while the other topics such as `avg`, `diff` etc have not.
This case is quite rare and we can keep it as is and see if it becomes common
in the future.
As for now, in order to avoid NPE for better error display I made a minor PR
for checking nulls:
