Jon Hermes commented on CASSANDRA-1105:
---------------------------------------
Should getting the file handle from a resource name be done once at creation
(file never expected to disappear, only change), or every time it checks for
modification (file can go away and we should explode when it does)?
> 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.
