Ariel Weisberg updated CASSANDRA-7544: -------------------------------------- Comment: was deleted (was: bq. ISTM that a discussion on the dev list is warranted. That's a pretty big "side effect" of this patch. It's not clear that it is? It sounds like you know something? I'd be happy to accept a patch ) > 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. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
