Sean Busbey commented on ACCUMULO-4415:
---------------------------------------

I can't have a single zookeeper instance shared between two Accumulo instances that have different instance secrets. This is a pretty big regression starting in AFAICT 1.7.

> 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.

> This affects at least the current 1.8 branch (1.8.0-SNAPSHOT), but I haven't checked earlier versions.
