Subject [jira] [Commented] (HBASE-4427) It would help to run a standalone HBase's ZK on a different port
Date Fri, 23 Sep 2011 07:36:26 GMT

    [ https://issues.apache.org/jira/browse/HBASE-4427?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13113221#comment-13113221

Lars George commented on HBASE-4427:
------------------------------------

I agree with JD and Stack, the change will mess up those setups that only use the defaults.
I think setting it explicitly by the user on both sides is the most sensible way. I thought
about using something like an increment, or fallbackClientPort that a cluster can use when
there is an existing ZK ensemble using the port. But then the clients would need to know where
to talk to, and might end up connecting to the wrong quorum because is uses its default ports
and there is someone now listening to it.

> 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?
