Ted Yu commented on KAFKA-5037:
-------------------------------
In KafkaStreams, I am adding the following method in order to detect state
transition of StreamThread:
{code}
/**
* An app can set a single {@link StreamThread.StateListener} so that the
app is notified when state changes.
*
* @param listener a new StreamThread state listener
* @throws IllegalStateException if this {@code KafkaStreams} instance is
not in state {@link State#CREATED CREATED}.
*/
public void setStreamThreadStateListener(StreamThread.StateListener
listener) {
{code}
Let me know whether a KIP is needed.
