[jira] [Created] (ZOOKEEPER-3776) Cluster stuck not forming up
quorum
Philipp created ZOOKEEPER-3776:
----------------------------------
Summary: Cluster stuck not forming up quorum
Key: ZOOKEEPER-3776
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3776
Project: ZooKeeper
Issue Type: Bug
Reporter: Philipp
We had working Zookeeper 3.4.8 that came with Kafka. 3 machines cluster. Now I'm trying to upgrade it to 3.6.0. I didn't touch the data directory, just set up 3.6.0 Zookeeper in the new directory and updated config. Stopped all Zookeepers. Now I've started eache Zk in turn with some delay. And they are not forming up quorum, stuck seemingly forever, sometimes trying to elect and sometimes throwing nonsensical errors.
For example, on node 1 (sorry don't know how to format this properly in jira):
