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.
