["Keith Turner (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ACCUMULO-2561?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14026492#comment-14026492 ] 

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.

> 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.
