Subject [jira] [Commented] (HBASE-4427) It would help to run a standalone HBase's ZK on a different port

Roman Shaposhnik commented on HBASE-4427:
-----------------------------------------

It is mostly out-of-the-box experience kind of question and you're absolutely right -- I can
set it in my hbase-site.xml. However, I would like to understand a little bit better why do
you think it'll be that disruptive. Suppose we change hbase-default.xml. The scenarious I
see are these:
   * standalone mode -- will work perfectly
   * pseudo-distributed mode (hbase.cluster.distributed == true) with embedded ZK -- will
work perfectly
   * pseudo-distributed mode (hbase.cluster.distributed == true) with standalone ZK (hbase.zookeeper.quorum
!= nul) -- will work perfectly since, as far as I understand, hbase.zookeeper.quorum will
override hbase.zookeeper.property.clientPort.
   * fully-distributed mode with standalone ZK -- see above. Little difference between where
the processes run, they will still require the same configs as far as hbase-site.xml is concerned.

Am I missing anything?

> It would be extremely helpful to have standalone HBase default to a non-standard port
for running its embedded ZK. This would help to run HBase on the same host where a legitimate
fully distributed ZK server, etc.
> It seems that the following addition to hbase-default.xml would be enough to make it
happen:
> {noformat}
> +  <property>
> +    <name>hbase.zookeeper.property.clientPort</name>
> +    <value>4181</value>
> +  </property>
> {noformat}
> This will take care of the master/client for HBase and can be overridden in hbase-site
if needed.
> Thoughts?
