Dave Marion commented on ACCUMULO-3694:
---------------------------------------

I'm pretty sure that you can run the dumpConfig admin command without needing 
the root password. Which means that you can capture all of the users and their 
granted permissions before you reset. This should help in recreating the users.

> Include root password recovery steps in docs

>             Project: Accumulo
>          Issue Type: Improvement
>          Components: docs
>            Reporter: Frans Lawaetz
>            Priority: Minor

> It would be helpful to add, perhaps in the Troubleshooting section of the 
> docs, the semi-hidden feature that is:
> accumulo init --reset-security
> As a stab:
> Q:  I've lost the accumulo root password, now what?
> A: Running "accumulo init --reset-security" will prompt you for a new root 
> password.  CAUTION: this command will delete all existing users.  You will 
> need to re-create all other users and set permissions accordingly.
