Subject Health Check Disabler
Date Wed, 08 Oct 2014 00:00:33 GMT
Hi Aurora,

I am currently working on a health check disabler for
https://issues.apache.org/jira/browse/AURORA-795

Review Board: https://reviews.apache.org/r/26383/

Here is a brief description:

The health check disabler is a way to temporarily disable health checks for
a running instance of a job.  The user can disable the health checks by
going to the instance’s sandbox and creating a special file that contains
the snooze duration.  After the snooze duration expires, the file is
deleted and health checks resume.  This is especially useful during heap
dumps, when the instance freezes and no longer responds to health checks.
The health check disabler is required in this case to prevent the health
checker from killing the job being heap dumped.

Thank you,

David Pan
