Keith Turner commented on ACCUMULO-1591:
----------------------------------------
Here is a more detailed scenario that describes the problem
# User installs 1.4.1
# User edits accumulo-site.xml and sets the secret to X
# User shuts down 1.4.1
# User installs 1.4.2
# Secret is not set in accumulo-site.xml and therefore reverts to default
# User starts 1.4.2
# 1.4.2 starts writes some zookeeper nodes using the default secret
# 1.4.2 is unable to read nodes written using the secret X
# 1.4.2 instance will not start up completely
# User kills 1.4.2 instance
# User edits accumulo-site.xml and sets the secret to X
# 1.4.2 still does not start properly because it can not read the nodes
written with the default secret
# User has to go into zookeeper and fix things
> Upgrading Accumulo with different zookeeper secret causes issues

> Key: ACCUMULO-1591
> URL: https://issues.apache.org/jira/browse/ACCUMULO-1591
> Project: Accumulo
> Issue Type: Bug
> Affects Versions: 1.4.0
> Reporter: Keith Turner
> Priority: Critical
> Fix For: 1.6.0
>
>
> A user ran into an issue where they upgraded Accumulo from 1.4.x to 1.4.y.
> During the process they changed the zookeeper password. This resulted in
> different nodes in zookeeper with different auths and which prevent Accumulo
> from working properly.
