Confuse created FLUME-3353:
------------------------------
Summary: Parameter allowTopicOverride should be changed to false
Key: FLUME-3353
URL: https://issues.apache.org/jira/browse/FLUME-3353
Project: Flume
Issue Type: Wish
Components: Sinks+Sources
Affects Versions: 1.9.0
Reporter: Confuse
In Flume 1.9.0, the default value of the allowTopicOverride parameter is false
in Kafka sink. Although instructions have been added to the user guide, this
is still not user-friendly when useing flume to transfer data from one Kafka
cluster to another Kafka cluster. Especially in the scenario that flume
upgrades from a lower version to a higher version while the topic in two Kafka
clusters is different. It will make user confused that user don't find the data
in second Kafka cluster. In general, setting this parameter to false is more
general. If user wants the same topic in two Kafka clusters, user can set this
parameter to be true. So, can the default value of this parameter be changed to
false ?
