-------------------------------------
Summary: [branch-1.0] Master should not bind to region server ports
Key: HBASE-13479
URL: https://issues.apache.org/jira/browse/HBASE-13479
Project: HBase
Issue Type: Sub-task
Reporter: Enis Soztutar
Priority: Blocker
Fix For: 1.0.1
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.
