we often meet publishing failure first time, and from the etcd logs, it seems that etcd won't publish again until the timer (duration is 8s) expires. so it will delay the ectd service about 8s. so we want to know:

1. why don't etcd publish again just after the previous publishing fails?
2. is there any way to shorten the duration of the timer?
   thanks!

attach part of the etcd logs:
