Subject [jira] [Commented] (ZOOKEEPER-2901) Session ID that is negative causes mis-calculation of Ephemeral Type

    I think it needs to do the same thing whether it's in standalone mode or not. Least surprise.
Also folks might want to test in standalone mode with the same basic configuration that they
use with an ensemble size > 1. They'd want the same behavior. I'd say it should work the
same regardless whether it's standalone or not.

>             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.
