>             Project: ZooKeeper
>          Issue Type: Bug
>          Components: server
>    Affects Versions: 3.4.9, 3.5.2, 3.4.11
>            Reporter: Michael Han

> In ZK documentation, we have:
> "The myid file consists of a single line containing only the text of that machine's id. So myid of server 1 would contain the text "1" and nothing else. The id must be unique within the ensemble and should have a value between 1 and 255."
> This however is not enforced in code, which should be fixed either in documentation that we remove the restriction of the range 1-255 or in code we enforce such constraint.
>  Discussion thread:
>  [http://zookeeper-user.578899.n2.nabble.com/Is-myid-actually-limited-to-1-255-td7581270.html]
