Hi, Related to https://mail-archives.apache.org/mod_mbox/flink-dev/201709.mbox/%3CCA+faj9yvPyzmmLoEWAMPgXDP6kx+0oed1Z5k4s3K9sgiCFyb=w...@mail.gmail.com%3E and https://issues.apache.org/jira/browse/FLINK-10052, I was wondering if there's a way to prevent Flink instances from failing while doing a rolling restart on ZK followers while still keeping the quorum?
This is what was shown in Flink logs while restarting ZK : ZooKeeper connection SUSPENDING. Changes to the submitted job graphs are not monitored (temporarily). I was able to reproduce this twice with a quorum of 5 ZK nodes while doing some ZK maintenance. Thanks! Kenzyme Le
