Paolo Patierno created KAFKA-5446:
-------------------------------------
Summary: Annoying braces showed on log.error using streams
Key: KAFKA-5446
URL: https://issues.apache.org/jira/browse/KAFKA-5446
Project: Kafka
Issue Type: Improvement
Components: streams
Reporter: Paolo Patierno
Priority: Trivial
Hi,
in the stream library seems to be a wrong usage of the log.error method when we
want to show an exception. There are useless braces at the end of the line
before showing exception information like the following example :
ERROR task [0_0] Could not close task due to {}
(org.apache.kafka.streams.processor.internals.StreamTask:414)
org.apache.kafka.clients.consumer.CommitFailedException: Commit cannot be
completed since the group has already rebalanced and assigned the partitions to
another member. This means that the time between subsequent calls to poll() was
longer than the configured max.poll.interval.ms, which typically implies that
the poll loop is spending too much time message processing. You can address
this either by increasing the session timeout or by reducing the maximum size
of batches returned in poll() with max.poll.records.

at
org.apache.kafka.clients.consumer.KafkaConsumer.commitSync(KafkaConsumer.java:1146)
as you can see in ".... due to {}", the braces aren't needed for showing
exception info so they are printed.
Thanks,
Paolo.
