Subject [jira] [Commented] (ACCUMULO-1591) Upgrading Accumulo with different zookeeper secret causes issues
Date Mon, 22 Jul 2013 15:28:48 GMT


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:
$ ./bin/accumulo org.apache.accumulo.server.util.ChangeSecret --old oldpasswd --new newpassword

The problem here was that the new servers had scribbled data using the new secret, yet could
not update things with the old secret.

> 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.
