Sijie Guo commented on BOOKKEEPER-118:
--------------------------------------
in hedwig java client, we did close old subscription channels in
SubscribeResponseHandler when it is not a SUCCESS response.
{code}
// Main method to handle Subscribe responses from the server that we sent
// a Subscribe Request to.
public void handleSubscribeResponse(PubSubResponse response, PubSubData
pubSubData, Channel channel)
throws Exception {
// If this was not a successful response to the Subscribe request, we
// won't be using the Netty Channel created so just close it.
if (!response.getStatusCode().equals(StatusCode.SUCCESS)) {
HedwigClientImpl.getResponseHandlerFromChannel(channel).channelClosedExplicitly
= true;
channel.close();
}
...
}
{code}
this issue just happens in hedwig cpp client.
> Hedwig client doesn't kill and remove old subscription channel after
> redirection.

> Currently we found that hedwig cpp client doesn't kill and remove old
> subscription channels after redirection, so there is lots of unused channels.
> Not sure whether hedwig java client has the same issue, need to check it.
