Subject [jira] [Updated] (HBASE-10200) Better error message when HttpServer fails to start due to java.net.BindException
Date Mon, 29 Sep 2014 20:16:35 GMT

     [ https://issues.apache.org/jira/browse/HBASE-10200?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Kiran Kumar M R updated HBASE-10200:
------------------------------------
    Affects Version/s: 2.0.0
               Status: Patch Available  (was: Open)

This patch adds check to verify if {{hbase.master.info.bindAddress}} and {{hbase.regionserver.info.bindAddress}}
belong to host machine or not.

If address does not belong to the machine, then error message is logged and exception is thrown
during HTTP Server startup/

hbase.util.Addressing#isLocalAddress method is added to check if an address is local. This
method is from Hadoop netutils  but not reused(Its marked as Interface Private in Hadoop.)


Please review and let me know any suggestions.

This patch is for master (2.0.0) branch.

> This was due to hbase.master.info.bindAddress giving static address but Hoya allocates
master dynamically.
> Better error message should be provided: when bindAddress points another host than local
host, message should remind user to remove / adjust hbase.master.info.bindAddress config param
from hbase-site.xml
