Enrico Olivelli commented on ZOOKEEPER-3108:
--------------------------------------------

I would add a validation that if you have both server.id and myid file that must hold the
same value

>  deprecated myid file and use a new property "server.id" in the zoo.cfg

> When use zk in distributional model,we need to touch a myid file in dataDir.then write
a unique number to it.It is inconvenient and not user-friendly,Look at an example from other
distribution system such as kafka:it just uses broker.id=0 in the server.properties to indentify
a unique server node.This issue is going to abandon the myid file and use a new property such
as server.id=0 in the zoo.cfg. this fix will be applied to master branch,branch-3.5+,
> keep branch-3.4 unchaged.
