>                 URL: https://issues.apache.org/jira/browse/ACCUMULO-1050
>             Project: Accumulo
>          Issue Type: Bug
>          Components: master
>    Affects Versions: 1.4.0
>            Reporter: Keith Turner

> There is code in the master like the following.
> {code}
>   if (!lock.isLocked() && !watcher.gotLock && watcher.failureException == null) {
>      //assume tserver there
> }else{
>      //assume tserver lost lock
> }
> {code}
> In the else the master assumes it got the tserver lock and therefore the tserver lost its lock.  But the else could execute when the master failed to get a lock. This may cause the master  to kill tablet server when there is no reason to.
