Subject [jira] [Commented] (HBASE-7831) lightweight way to make RS commit suicide
Date Tue, 12 Feb 2013 18:37:12 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7831?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13576866#comment-13576866

Jean-Daniel Cryans commented on HBASE-7831:
-------------------------------------------

In HRS we have the concept of aborting on shutting down (abortRequested). It probably needs
improvement.

> There are times in the life of many a region server when it realizes that it cannot go
on any longer in the hostile, inhospitable environment. Or it might realize that there's something
inherently wrong with it on the inside (probably because a developer screwed up). The only
way out is killing itself.
> There's code in some places currently that does Runtime halt in such cases, and there
may be code that calls HRegionServer method to do this.
> I think we need some easy-to-access (lightweight interface, or static) way to trigger
reliable (no catching exceptions on the upper levels, etc.) RS death in such cases.
