Roger Schildmeijer commented on CASSANDRA-1053:
-----------------------------------------------
Summary from irc discussion.
* will a phi knob scare people of?
* will people change the knob without understanding how big the implication
will be (e.g from 8 to 16)
> Expose setting of phi in the FailureDetector

> Key: CASSANDRA-1053
> URL: https://issues.apache.org/jira/browse/CASSANDRA-1053
> Project: Cassandra
> Issue Type: Improvement
> Affects Versions: 0.6
> Reporter: Brandon Williams
> Priority: Trivial
>
> I've seen some users, always on cloud platforms, say that they have problems
> with hosts flapping in the FD. GC is not the cause. I know of at least one
> production deployment where they are already hacking phi to 10 to get around
> the flapping problems.
> This is a dangerous thing to expose, however, since giving meaning to the
> difference of 8 and 10 here is hard to quantify to someone unfamiliar with
> the inner workings. Perhaps we can allow setting it in the config, but not
> specify a default and leave it commented out with a big fat warning.
