Daniel Doubleday updated CASSANDRA-2662:
----------------------------------------
Attachment: dynsnitch.patch
One very simple fix is to initialize scores with 0 which forces at least one
read.
Dunno if thats a good idea when using multi dc snitches ...
> Nodes get ignored by dynamic snitch when read repair chance is zero
> -------------------------------------------------------------------

> Key: CASSANDRA-2662
> URL: https://issues.apache.org/jira/browse/CASSANDRA-2662
> Project: Cassandra
> Issue Type: Bug
> Components: Core
> Affects Versions: 0.7.6
> Reporter: Daniel Doubleday
> Priority: Trivial
> Attachments: dynsnitch.patch
>
>
> DynamicEndpointSnitch falls back to subsnitch when one of the scores of the
> endpoints being compared is missing.
> This leads to a stable order of hosts until reads will lead to recorded
> scores.
> If setting read repair chance to 0 and reads are performed with quorum then
> (rf - # quorum nodes) will never get reads.
