----------------------------------
Summary: Reduce server log verbosity at info level
Key: KAFKA-2175
URL: https://issues.apache.org/jira/browse/KAFKA-2175
Project: Kafka
Issue Type: Improvement
Components: controller, zkclient
Affects Versions: 0.8.3
Reporter: Todd Palino
Assignee: Neha Narkhede
Priority: Minor
Currently, the broker logs two messages at INFO level that should be at a lower
level. This serves only to fill up log files on disk, and can cause performance
issues due to synchronous logging as well.
The first is the "Closing socket connection" message when there is no error.
This should be reduced to debug level. The second is the message that ZkUtil
writes when updating the partition reassignment JSON. This message contains the
entire JSON blob and should never be written at info level. In addition, there
is already a message in the controller log stating that the ZK node has been
updated.
