Chris Nauroth resolved ZOOKEEPER-4430.

    Resolution: Not A Problem

Hello [~Caelebs].

I'm not sure we've made this easily discoverable in documentation, but -101 corresponds to a {{NONODE}} error:

https://github.com/apache/zookeeper/blob/release-3.5.1/src/java/main/org/apache/zookeeper/KeeperException.java#L360

https://github.com/apache/zookeeper/blob/release-3.5.1/src/java/main/org/apache/zookeeper/KeeperException.java#L255

For example, attempting a setData call on a znode that doesn't exist could return this error.

I think this issue was informational in nature and not really reporting a ZooKeeper bug, so I'll close it now. I hope this helps.

> I found that there is an error code of `error -101` in the transaction log of zookeeper, But I can't find any valid information about this error, so I don't know what this error means and does it have any impact?
