>                 Key: ZOOKEEPER-2901
>                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2901
>             Project: ZooKeeper
>          Issue Type: Bug
>          Components: server
>    Affects Versions: 3.5.3
>         Environment: Running 3.5.3-beta in Docker container
>            Reporter: Mark Johnson
>            Assignee: Jordan Zimmerman
>            Priority: Blocker

> In the code that determines the EphemeralType it is looking at the owner (which is the
client ID or connection ID):
> EphemeralType.java:
>    public static EphemeralType get(long ephemeralOwner) {
>        if (ephemeralOwner == CONTAINER_EPHEMERAL_OWNER) {
>            return CONTAINER;
>        }
>        if (ephemeralOwner < 0) {
>            return TTL;
>        }
>        return (ephemeralOwner == 0) ? VOID : NORMAL;
>    }
> However my connection ID is:
> header.getClientId(): -720548323429908480
> This causes the code to think this is a TTL Ephemeral node instead of a
> NORMAL Ephemeral node.
> This also explains why this is random - if my client ID is non-negative
> then the node gets added correctly.
