We accidently configured our cluster with SimpleSnitch (instead of
PropertyFileSnitch) and dynamic_snitch: true. This is with version
0.7.0.
We saw the errors below on get_slice and batch_mutate calls. The
errors went away when we switched to PropertyFileSnitch.
Should dynamic_snitch work with SimpleSnitch? Should I open a Jira issue?
