Subject About ZooKeeper Dynamic Reconfiguration
Date Wed, 21 Aug 2019 10:00:10 GMT
Hi
   I encounter a problem which blocks my development of load balance using ZooKeeper 3.5.5.
   Actually, I have a ZooKeeper cluster which comprises of five zk servers. And the dynamic
configuration file is as follows:

  server.1=zk1:2888:3888:participant;0.0.0.0:2181
  server.2=zk2:2888:3888:participant;0.0.0.0:2181
  server.3=zk3:2888:3888:participant;0.0.0.0:2181
  server.4=zk4:2888:3888:participant;0.0.0.0:2181
  server.5=zk5:2888:3888:participant;0.0.0.0:2181

  The zk cluster can work fine if every member works normally. However, if say two of them
are suddenly down without previously being notified,
the dynamic configuration file shown above will not be synchronized dynamically, which leads
to the zk cluster fail to work normally.
  I think this is a very common case which may happen at any time. If so, how can we resolve
it?
  Really look forward to hearing from you!
Thanks
