>                 URL: https://issues.apache.org/jira/browse/ACCUMULO-4637
>             Project: Accumulo
>          Issue Type: Bug
>    Affects Versions: 1.7.2
>            Reporter: John Vines
>            Priority: Major
>             Fix For: 1.9.0, 2.0.0
> Saw at a customer where one of their servers had not been properly synced. 
> Specifically, one of the instance values was mismatched, which means the 
> system password was mismatched. Server logs show a lot of bad auth failures 
> for the system user (as expected).
> Meanwhile, the master is spinning, trying to get all the tablets online, 
> constantly attempting to assign them to this one server (because it has 0 
> assigned, so it's a prime contender). Instead of this behavior, the master 
> should rip out the servers zk lock because it's not a member of the cluster 
> anymore (not until it's accumulo-site is fixed).
