[jira] [Created] (HBASE-7831) lightweight way to make RS commit suicide

Sergey Shelukhin created HBASE-7831:
---------------------------------------

             Summary: lightweight way to make RS commit suicide
                 Key: HBASE-7831
                 URL: https://issues.apache.org/jira/browse/HBASE-7831
             Project: HBase
          Issue Type: Improvement
            Reporter: Sergey Shelukhin
            Priority: Minor


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.
