Kurt Greaves commented on CASSANDRA-7544:

[~aweisberg] one nit: 
 if statement uses a bitwise OR in place of a logical OR. While the behaviour 
is the same, can you ninja a fix? Just to save us when the condition gets 
changed in the future and someone doesn't notice.

> Allow storage port to be configurable per node

>                 Key: CASSANDRA-7544
>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-7544
>             Project: Cassandra
>          Issue Type: Improvement
>            Reporter: Sam Overton
>            Assignee: Ariel Weisberg
>            Priority: Major
>             Fix For: 4.0
> Currently storage_port must be configured identically on all nodes in a 
> cluster and it is assumed that this is the case when connecting to a remote 
> node.
> This prevents running in any environment that requires multiple nodes to be 
> able to bind to the same network interface, such as with many automatic 
> provisioning/deployment frameworks.
> The current solutions seems to be
> * use a separate network interface for each node deployed to the same box. 
> This puts a big requirement on IP allocation at large scale.
> * allow multiple clusters to be provisioned from the same resource pool, but 
> restrict allocation to a maximum of one node per host from each cluster, 
> assuming each cluster is running on a different storage port.
> It would make operations much simpler in these kind of environments if the 
> environment provisioning the resources could assign the ports to be used when 
> bringing up a new node on shared hardware.
> The changes required would be at least the following:
> 1. configure seeds as IP:port instead of just IP
> 2. gossip the storage port as part of a node's ApplicationState
> 3. refer internally to nodes by hostID instead of IP, since there will be 
> multiple nodes with the same IP
> (1) & (2) are mostly trivial and I already have a patch for these. The bulk 
> of the work to enable this is (3), and I would structure this as a separate 
> pre-requisite patch.
