> Master should not bind to region server ports

> Project: HBase
> Issue Type: Improvement
> Reporter: Enis Soztutar
> Assignee: Devaraj Das
> Priority: Critical

>
> In 1.0, master by default binds to the region server ports (rpc and info). We
> have done it so thinking that in the long term, master and meta co-location
> will be default, and we can merge the master and region server as a single
> daemon.
> Over at HBASE-11165, if the conclusion end up being that meta will not be
> colocated at all, then master hosting a region server will just become an
> implementation detail. [[email protected]] says that we might never allow
> master to host regions.
> Now, we are stuck in a state where we have made master bind to RS ports in
> 1.0, which might create some confusion (and frustration) for small cluster
> users who traditionally used to host a master and a region server on the same
> node.
> I think we should undo this in 1.1 and use the previous master ports (16000)
> and not bind to 16030, so that the user does not need to do anything to bring
> up a RS on the same host. At least users going from 0.98 -> 1.1 will not take
> a hit. Users going from 1.0 -> 1.1 will see changed default ports.
