Eric Newton commented on ACCUMULO-1591:
---------------------------------------
Assuming that the user knows they are going to change the system password, they
can do:
1. Put the new secret in accumulo-site.xml and distribute this file throughout
the cluster
2. Run ChangeSecret:
{noformat}
$ ./bin/accumulo org.apache.accumulo.server.util.ChangeSecret --old oldpasswd
--new newpassword
{noformat}
The problem here was that the new servers had scribbled data using the new
secret, yet could not update things with the old secret.
> Upgrading Accumulo with different zookeeper secret causes issues

> Project: Accumulo
> Issue Type: Bug
> Affects Versions: 1.4.0

> 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.
