> Tracer incorrectly uses instance.secret for its /tracers area in ZooKeeper.
> The tracer does not use the Accumulo system credentials, and instead uses a 
> specific tracer username and password. It should also not use the 
> instance.secret (which is for the system credentials).
> A side effect of this bug is that ChangeSecret does not update the /tracers 
> ACLs in ZooKeeper, preventing the tracer from working entirely after the 
> instance.secret is changed.
> The following error will be seen in the monitor after the ChangeSecret tool 
> is run.
> {code}
> Thread 'tracer' died.
