> For HBase clusters running on unusual networks (such as NAT'd cloud
> environments or physical machines with multiple IP's per network interface)
> it would be ideal to have a way to both specify:
> # which IP interface to which HBase master or region-server will bind
> # what hostname HBase will advertise in Zookeeper both for a master or
> region-server process
> While efforts such as HBASE-8640 go a long way to normalize these two sources
> of information, it is not possible in the current design of the properties
> available to an administrator for these to be unambiguously specified.
> One has been able to request {{hbase.master.ipc.address}} or
> {{hbase.regionserver.ipc.address}} but one can not specify the desired HBase
> {{hbase.master.hostname}}. (It was removed in HBASE-1357, further I am
> unaware of a region-server equivalent.)
> I use a configuration management system to generate all of my configuration
> files on a per-machine basis. As such, an option to generate a file
> specifying exactly which hostname to use would be helpful.
> Today, specifying the bind address for HBase works and one can use an
> HBase-only DNS for faking what to put in Zookeeper but this is far from
> ideal. Network interfaces have no intrinsic IP address, nor hostname.
> Specifing a DNS server is awkward as the DNS server may differ from the
> system's resolver and is a single IP address. Similarly, on hosts which use a
> transient VIP (e.g. through keepalived) for other services, it means there's
> a seemingly non-deterministic hostname choice made by HBase depending on the
> state of the VIP at daemon start-up time.
> I will attach two networking examples I use which become very difficult to
> manage under the current properties.
