Subject Re: gracefully remove a node from the ensamble
Date Fri, 14 Jul 2017 01:19:22 GMT
Hi Luigi,

In 3.5.X yes: https://zookeeper.apache.org/doc/trunk/zookeeperReconfig.html

For previous releases (3.4 etc) you would need to do a rolling restart,
where for each server you change the config file to exclude that member
and bounce the server. Preferably do this one server at a time, and let the
ensemble be operational before bouncing the next server. And bounce
the leader last. I wouldn't call this gracefully though :)
