I recently upgraded from 3.4.3 to 3.4.4 and it seems that "leaderServes" is now false by default (my leader would not take clients until I manually set this flag to true).
I didn't see anything in the Release Notes about it which was surprising... Also, my zkCli.sh command now crashes a bunch...though I can still run the 3.4.3 zkCli.sh just fine against my cluster. Brian -- http://about.me/BrianTarbox
