Enis Soztutar resolved HBASE-13479.
-----------------------------------
Resolution: Fixed
Release Note:
HBase master now respects the configuration hbase.master.port if set. By
default it is not set in hbase-default.xml in 1.0.x releases. Master also
respects the parameter hbase.master.info.port, which is not changed. However,
master will not bind to hbase.regionserver.info.port anymore. It only binds to
hbase.master.info.port.
The behavior:
1.0.0:
RPC: hbase.master.port IS NOT respected. Master binds to hbase.regionserver.port
INFO: Master binds to hbase.master.info.port AND hbase.regionserver.info.port.
By default, master will use: 16010, 16020, 16030
1.0.1+:
RPC: hbase.master.port IS respected if configured. Master binds to
hbase.regionserver.port by default if not configured.
INFO: Master binds to hbase.master.info.port only.
By default, master will use: 16010, 16020.
Hadoop Flags: Reviewed
I have committed this to 1.0. Thanks for reviews and trying it out.

> In parent jira, we have brought back old config value {{hbase.master.port}}
> and made it so that if it is configured (which is by default), master does
> not bind to the region servers's RPC and info ports now. We have realized
> that master binding to RS ports turns out to be a pain point and unnecessary
> frustration for users (although we were expecting the opposite).
> Let's use this jira to see what we can do in 1.0.x series. In 1.0.0, master
> binds to ports
> {{hbase.regionserver.port}}
> {{hbase.master.info.port}}
> {{hbase.regionserver.info.port}}
> In 1.0.x, we have a couple of options I think:
> (a) don't do anything.
> (b) Commit patch from master as it is. All upgrades from 1.0.0 will observe
> changed ports.
> (c) Commit the patch, disabled by default. If user has {{hbase.master.port}}
> set, bind to the port. Only users who set the conf value will observe changed
> ports.
> (d) Commit the patch with an extra config option
> {{hbase.master.compat.mode}}. The users have to explicitly enable this in
> 1.0.
