Subject [jira] [Commented] (ACCUMULO-3622) admin tool for reseting passwords stored in ZKAuthenticator
Date Wed, 25 Feb 2015 00:11:06 GMT


Sean Busbey commented on ACCUMULO-3622:

It looks like that will erase and rewrite everything under the user node for the root user.
Can we quantify what will be destroyed by reseting the perms for system, namespace, etc?

I think since we're talking about the root user those all get ignored maybe?

>                 URL:
>             Project: Accumulo
>          Issue Type: Improvement
>          Components: zookeeper
>    Affects Versions: 1.5.0, 1.6.0
>            Reporter: Sean Busbey
>            Priority: Critical
>              Labels: operations, supportability
>             Fix For: 1.5.3, 1.7.0, 1.6.3
> For clusters that rely on the ZKAuthenticator, we should add an admin tool that will
do password resets outside of the shell. The tool will need to be supplied the ZK quorum,
the instance-id (or name), and the instance secret.
> The main use case here is should a change management failure happen that results in losing
the root user password.
> Currently, when users face this problem their only option is to access ZK's restricted
properties directly with the instance secret (via ACCUMULO-2469) and then overwrite the contents
of the node {{/accumulo/<instance id>/users/root}} with the following byte array (per
for 1.6.z):
> {code}
> [8 byte salt][32 byte output of SHA-256([UTF8 bytes of password][8 byte salt])]
> {code}
> The tool should live with the other non-public-api internal tools (server/base/src/main/java/org/apache/accumulo/server/util/).
