> Key: ZOOKEEPER-3906
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3906
> Project: ZooKeeper
> Issue Type: Bug
> Components: quorum
> Affects Versions: 3.5.7
> Reporter: Gangadhar
> Priority: Major
>
> *Issue*: Data Inconsistency Between Zookeeper Leader and zookeeper Followers.
> zookeeper followers and zookeeper leaders have other information. We try to
> delete the information from the follower's, but information not present in
> zookeeper leader, it's throwing error like *Node does not exist:*
> *Expected behaviour:* Data consistency between zookeeper leader and Zookeeper
> followers should be same.
>
> Steps followed as part of troubleshooting:
> We have 5 zookeepers in clusters.
> *Step1:* verified all zookeepers are following the leader or not?. As per
> below information its following all 4 zookeepers to zookeeper leader
> zk_version 3.5.7-f0fdd52973d373ffd9c86b81d99842dc2c7f660e, built on

> *Step 2:* Verified znode in all the zookeepers , but we are not getting same
> information from zookeeper leader and followers.
> *Step 3:* Try to delete the Zookeeper node and received below error. Also, we
> are suspecting that when trying to delete the info of znode, it's trying to
> reach zookeeper leader and throwing *Node does not exist* error.
