When you set on an empty path, the zookeeper will crash

[geo-turcsanyi]

When you try setting data on an empty path, it will crash and burn your zookeeper server. And by this I mean data corruption, you need to empty your data directory and then restart it, otherwise nobody will be able to connect to it any more and will get a connection refused.

It would be nice to have an error if the path is empty, rather than letting the set happen and watching your zookeeper go down in style.

Hi,

Can you give more details:

• Which version you are using
• The code snip that caused this
• Any suspicious logs?

Thanks!

This is a bug in zookeeper, see https://issues.apache.org/jira/browse/ZOOKEEPER-2213

Thanks for reporting this.

While it certainly seems like the server should handle this more gracefully, I added a client side check to be safe.

I create a ticket to have the logic in this package match the Java client: #63
