Martin Vysny updated KAFKA-7016:
--------------------------------
Description:
I am trying to write a Kafka Consumer; upon running it only prints out:
{\{ org.apache.kafka.common.errors.InvalidGroupIdException: The configured
groupId is invalid}}
Note that the stack trace is missing, so that I have no information which part
of my code is bad and need fixing; I also have no information which Kafka
Client method has been called. Upon closer examination I found this in
ApiException:
{{/* avoid the expensive and useless stack trace for api exceptions */}}
{{@Override}}
{{public Throwable fillInStackTrace() {}}
\{{ return this;}}
{{}}}
I think it is a bad practice to hide all useful debugging info and trade it for
dubious performance gains. Exceptions are for exceptional code flow which are
allowed to be slow.
This applies to kafka-clients 1.1.0
