Subject [jira] [Created] (ACCUMULO-1652) Provide hooks to customize OnOutOfMemoryError behavior
Date Tue, 13 Aug 2013 17:03:48 GMT
Drew Farris created ACCUMULO-1652:
-------------------------------------

             Summary: Provide hooks to customize OnOutOfMemoryError behavior
                 Key: ACCUMULO-1652
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-1652
             Project: Accumulo
          Issue Type: Improvement
          Components: scripts
    Affects Versions: 1.5.0, 1.4.3
            Reporter: Drew Farris
            Priority: Minor


Currently, the accumulo startup script hardcodes {{OnOutOfMemoryError}} behavior to be {{kill
-9 %p}}. Perhaps this could be modified to call a script.

for example: {noformat}-XX:OnOutOfMemoryError="${ACCUMULO_HOME}/bin/oom.sh %p $1"{noformat}
whose default behavior implementation is {{kill -9}}, but this can be modified by the administrator
to implement other behavior (e.g. do a {{jstack}} first).

This has the added benefit of being able to modify the behavior at runtime without restarting
processes.
