             Summary: Slave attributes cached incorrectly by scheduler
                 Key: AURORA-582
                 URL: https://issues.apache.org/jira/browse/AURORA-582
             Project: Aurora
          Issue Type: Bug
          Components: Scheduler
            Reporter: Kevin Burg
            Priority: Critical


I would like to be able to update the attributes being offered by a slave after the cluster has been setup. The cluster was initialized with two slaves reporting two attributes - 'host' and 'rack'. I was able to assign task with constraints involving these two attributes and everything works. Any third attribute I add shows up in the '/offers' endpoint of the aurora process, but not in the '/slaves' endpoint. Modifications to existing attributes are similarly not reflected. I am not able to schedule tasks involving a constraint on the third attribute or on any modified attributes. The schedule requests just end in vetoes from both slaves unable to resolve the constraints.

It's been suggested that I delete the slave's 'meta' directory before bouncing the slave, but this has not helped to solve the issue. The only way I have been able to modify the attributes so that aurora can see them is by deleting the entire AURORA_ROOT and rebuilding the cluster.
