Dear Apache ZooKeeper Committee,
I hope this email finds you well. I am reaching out to bring to your attention a potential bug that I have discovered in the Apache ZooKeeper code while working on a project. I have noticed that the behavior of PERSISTENT, EPHEMERAL, CONTAINER, and TTL nodes is as expected. However, when trying to access the type by checking the EphemeralOwner parameter of a node's stat, it returns the same value (0x0) for all node types except EPHEMERAL. This suggests that there may be an issue with the implementation of EphemeralType.get(). I am using Zookeeper version 3.6. To reproduce this issue I activated Zookeeper extended usage and created different nodes of different types. They all behave as expected but the EphemeralOwner parameter is 0x0. This conflicts with the documentation https://zookeeper.apache.org/doc/r3.6.3/apidocs/zookeeper-server/index.html. I would like to inquire if there is another way of retrieving the node type or if this is indeed a bug in the code. If so, I would be grateful if you could provide me with any relevant documentation or code references that I can use to further understand the issue. Thank you for your time and efforts in maintaining Apache ZooKeeper. I look forward to hearing back from you soon. Best regards, Marcos
