Divij Vaidya updated KAFKA-15341:
---------------------------------
Description:
When we are in a rolling restart to enable TS at system level, some brokers
have TS enabled on them and some don't. We send an alter config call to enable
TS for a topic, it hits a broker which has TS enabled, this broker forwards it
to the controller and controller will send the config update to all brokers.
When another broker which doesn't have TS enabled (because it hasn't undergone
the restart yet) gets this config change, it "should" fail to apply it. But
failing now is too late since alterConfig has already succeeded since
controller->broker config propagation is done async.
With this JIRA, we want to have controller check if TS is enabled on all
brokers before applying alter config to turn on TS for a topic.
