Sean Busbey created HBASE-24667:
-----------------------------------
Summary: Rename config that disables reverse DNS to put it in
hbase.unsafe
Key: HBASE-24667
URL: https://issues.apache.org/jira/browse/HBASE-24667
Project: HBase
Issue Type: Task
Components: conf, Operability
Reporter: Sean Busbey
HBASE-18226 added a config for disabling reverse DNS checks
{{hbase.regionserver.hostname.disable.master.reversedns}} and the release note
calls out that the config is dangerous:
{quote}
he following config is added by this JIRA:
hbase.regionserver.hostname.disable.master.reversedns
This config is for experts: don't set its value unless you really know what you
are doing.
When set to true, regionserver will use the current node hostname for the
servername and HMaster will skip reverse DNS lookup and use the hostname sent
by regionserver instead. Note that this config and hbase.regionserver.hostname
are mutually exclusive. See https://issues.apache.org/jira/browse/HBASE-18226
for more details.
Caution: please make sure rolling upgrade succeeds before turning on this
feature.
{quote}
We should make clear the risks of using this config by making sure the name
starts with {{hbase.unsafe}}.
Rename {{{{hbase.regionserver.hostname.disable.master.reversedns}} to
{{}}{{hbase.unsafe.regionserver.hostname.disable.master.reversedns}}{{}} but
make sure the former is kept with a "deprecated config name" warning.}}
