Subject [jira] Resolved: (HBASE-1279) Fix the way hostnames and IPs are handled
Date Mon, 04 May 2009 18:35:30 GMT

     [ https://issues.apache.org/jira/browse/HBASE-1279?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Jean-Daniel Cryans resolved HBASE-1279.

      Resolution: Fixed
    Release Note: To tell HBase how to use your DNS configuration, set hbase.regionserver.dns.interface
and hbase.regionserver.dns.nameserver in hbase-site.xml just like in hadoop-site.xml

I tested my patch against 2 clusters at openplaces, one with dns problems and one with no
problem at all. On the first by setting the new configs from hbase-default the hostnames were
now correctly set and on the second one nothing was changed.

> Yes, I've unlocked the port, and i am actually able to access from the web
> UI with a client not running on EC2 to HBase at example.com:60010. It shows
> all User Tables, but the Region Servers Address is the EC2 internal address:
> domU-12-31-39-00-65-E5.compute-1.internal:60020.
> I guess the client fails because it can not connect region server, which
> serves only for an internal IP. However, in hbase-site.xml, I did configure
> with region server explicitly in its external IP.

> In fact we completely bypass the hostname set in hbase.regionserver, also the hostnames
in the web UI are not the good ones. We should do that part like hadoop does.
