What's the plan for deprecating this? Keeping this parameter around forever
seems like a bad idea. Adds complication that we don't really need to carry
around. Perhaps we can deprecate in 3.5.4 and remove in 3.5.5? Similarly I
don't think we should include this at all in 3.6.0 (trunk).

> 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.
