Subject [jira] [Created] (ACCUMULO-4415) Tracer requires instance.secret
Date Thu, 18 Aug 2016 22:26:20 GMT
Christopher Tubbs created ACCUMULO-4415:

             Summary: Tracer requires instance.secret
                 Key: ACCUMULO-4415
             Project: Accumulo
          Issue Type: Bug
            Reporter: Christopher Tubbs

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

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.

Thread 'tracer' died.

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