Brandon Williams commented on CASSANDRA-2940:
---------------------------------------------

If I understand correctly, the preferred approach would be something like this:
-New methods in StorageProxyMBean expose this property.
-StorageProxy implements this as a call to the new static method
DatabaseDescriptor.setRpcTimeout(Long).
-DatabaseDescriptor.setRpcTimeout(Long) changes the value of
Config.rpc_timeout_in_ms (notice that my understanding is that we should keep
this as it is, so that the default value can still be loaded from the yaml file
if needed).

Yes, this is correct, we should never be rewriting the yaml. Thanks!

> When using the hadoop integration especially, experimenting with
> rpc_timeout_in_ms is a pain if you have to restart every server in the
> cluster for it to take effect. This would be an improvement to make it into
> a jmx mbean property to set it at runtime. The yaml file could be updated
> separately so it would be persistent still.
