Subject [jira] [Commented] (HBASE-14236) A bug in Reference Guide, Quick Start section
Date Tue, 18 Aug 2015 17:05:46 GMT

    [ https://issues.apache.org/jira/browse/HBASE-14236?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14701600#comment-14701600

kramerli commented on HBASE-14236:

Thanks for the reply.

Yes, quick start should has minimal required config.
However the advanced section is also part of the quick start. http://hbase.apache.org/book.html#quickstart_fully_distributed

Newbee who follow the instruction to setup the env and find there is fatal error will feel
very frustrated.

My suggestion is to add some text like this:

Please be noted that in current Hbase version, the master or backup master server is also
a type of region server. So when you decide to start the region server and backup master on
the same node for example node-b.example.com. It will hit error as the port can be used for
only one of them.

To resolve this issue you can edit config/hbase-site.xml add below config


This will force the region server to use some different port to avoid the conflict.  

I think the text can be added at the "Procedure: Prepare node-b and node-c".  :)

>             Project: HBase
>          Issue Type: Bug
>          Components: documentation
>    Affects Versions:
>         Environment: CentOS Linux release 7.1.1503 (Core) 
>            Reporter: kramerli
>             Fix For:
>   Original Estimate: 1h
>  Remaining Estimate: 1h
> This is an error on online documation.  (http://hbase.apache.org/book.html#_get_started_with_hbase
> To locate the error you can go to 
> 2.2. Get Started with HBase
> Example 2. Example hbase-site.xml for Standalone HBase
> The config example here do not specify a port for the region server. So When you go to
the 2.4 Advanced - Fully Distributed (http://hbase.apache.org/book.html#quickstart_fully_distributed).
You will hit error.
> Because the region server will conflict with backup master or master. As they use the
same port.
> People who read this section are always newbee, this will confuse them.
