Keith Turner commented on ACCUMULO-2561:
----------------------------------------
Also, halt is used to avoid shutdown hooks. Sometimes shutdown hooks can keep
the process alive and threads within the process operating. When a tserver
loses its lock, it needs to stop operating ASAP.
> Make o.a.a.server.util.Halt test-friendly

> Issue Type: Improvement
> Reporter: Bill Havanki
> Priority: Minor
> Labels: newbie, testability
>
> The various servers use {{o.a.a.server.util.Halt}} to terminate the JVM if
> something goes wrong. {{Halt}} class calls {{Runtime.halt()}}, which of
> course would torpedo any testing going on. The mechanism should be reworked
> to not kill the JVM in a test scenario.
