Flavio Junqueira commented on ZOOKEEPER-2503:
---------------------------------------------
I agree that the range [1, 255] should be sufficient to cover virtually every
case we have. Perhaps not even extreme cases with a ton of observes would need
more than that. I'm wondering about if there is any issue with automating
configuration. I can't think of anything, but we should ask around.
> Inconsistency between myid documentation and implementation

> Key: ZOOKEEPER-2503
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2503
> Project: ZooKeeper
> Issue Type: Bug
> Components: server
> Affects Versions: 3.4.9, 3.5.2
> Reporter: Michael Han
> Fix For: 3.5.3, 3.4.10
>
>
> 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
