Subject callback handler is not getting called if cluster is down
Date Mon, 08 Jun 2015 07:27:45 GMT

we are using .8.2.0 broker and default async producer to send the message*.
we recently found out that if whole cluster gets down then callback handler
is not getting called while we are getting below exception continuously*

*12:36:41,267# WARN  [Selector] - Error in I/O with localhost/
<>java.net.ConnectException: Connection refusedat
sun.nio.ch.SocketChannelImpl.checkConnect(Native Method)*

I want to know is there any way I can catch to figure out cluster is
down problematically  and log all the failed message so that it can be
retry later after cluster state changes.
