Edward Ribeiro commented on ZOOKEEPER-1404:
-------------------------------------------
Sorry, I read quickly and forgot that "j < i and n_j is a znode in C" while
writing my comment.
> leader election pseudo code probably incorrect

> Key: ZOOKEEPER-1404
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1404
> Project: ZooKeeper
> Issue Type: Bug
> Components: documentation
> Affects Versions: 3.4.3
> Reporter: Robert Varga
>
> The pseudo code for leader election in the recipes.html page of 3.4.3
> documentation is the following...
> {quote}
> Let ELECTION be a path of choice of the application. To volunteer to be a
> leader:
> 1.Create znode z with path "ELECTION/guid-n_" with both SEQUENCE and
> EPHEMERAL flags;
> 2.Let C be the children of "ELECTION", and i be the sequence number of z;
> 3.Watch for changes on "ELECTION/guid-n_j", where j is the
> {color:red}*smallest*{color} sequence number such that j < i and n_j is a
> znode in C;
> Upon receiving a notification of znode deletion:
> 1.Let C be the new set of children of ELECTION;
> 2.If z is the smallest node in C, then execute leader procedure;
> 3.Otherwise, watch for changes on "ELECTION/guid-n_j", where j is the
> {color:red}*smallest*{color} sequence number such that j < i and n_j is a
> znode in C;
> {quote}
> I think, in both third steps *highest* should appear instead of
> {color:red}*smallest*{color}.
