cloud version is Brixton.SR1....
i use sping-cloud-bus-kafka and sping-cloud-zookeeper-all (using zookeeper to discovery) ,every time ,there are two items in zookeeper,as :
zookeeper data : zookeeper data image
my yml is: my yml
when started, it create applicationcontext twice , kafka producer twice, zookeeperclient twice, the stack trace is:
first time:
