Jonathan Ellis commented on CASSANDRA-1105:
-------------------------------------------
A File object in Java is just a glorified String. You don't want to be opening
it here, just checking the mtime.
> Create timers to reload cassandra-rack.properties and datacenters.properties

> PropertyFileSnitch allows reloading changes from its config file manually.
> DatacenterShardStrategy doesn't allow reloading at all [after I ripped out
> the reload-for-each-getNaturalEndpoints call code, in CASSANDRA-1103].
> Let's check each of these for changes (modification time on the fs is
> sufficient) every minute and reload automatically if changes are seen. The
> manual-reload code from PFS can then be dropped.
