Subject Re: GSoC 2010: ZooKeeper Failure Detector Module
Date Wed, 05 May 2010 23:41:32 GMT
Hi Abmar, cool project!

I wrote an implementation of the Phi Accrual Detector which I would be
happy to donate. It has the nice property that its parameters are
based on expectation odds rather than something more arbitrary like #
retries.

You can steal it at http://github.com/arosien/failure. It works well
but let me know if you have any suggestions.
