[jira] [Created] (ZOOKEEPER-2213) Empty path in Set crashes server
and prevents restart
Brian Brazil created ZOOKEEPER-2213:
---------------------------------------
Summary: Empty path in Set crashes server and prevents restart
Key: ZOOKEEPER-2213
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2213
Project: ZooKeeper
Issue Type: Bug
Components: server
Affects Versions: 3.4.5
Reporter: Brian Brazil
Priority: Blocker
See https://github.com/samuel/go-zookeeper/issues/62
I've reproduced this on 3.4.5 with the code:
c, _, _ := zk.Connect([]string{"127.0.0.1"}, time.Second)
c.Set("", []byte{}, 0)
This crashes a local zookeeper 3.4.5 server:
2015-06-10 16:21:10,862 [myid:] - ERROR [SyncThread:0:SyncRequestProcessor@151] - Severe unrecoverable error, exiting

On restart the zookeeper server crashes out:
