 Key: HBASE-4671

  Issue Type: Bug
  Components: test
Affects Versions: 0.90.4
 Environment: At least Ubuntu 11.10 with a default hosts file.
Reporter: Ferdy Galema

 When /etc/hosts contains following lines (and this is not uncommon) it will 
 cause HBaseTestingUtility to malfunction.

 Workaround:
 Changing 127.0.1.1 to 127.0.0.1 works.
 Permanent solution:
 Dunno, my understanding of inner workings is not sufficient enough. Although 
 it seems like it has something to do with changing the machine name from 
 myMachineName to localhost during the test:

From the hbase reference guide: http://hbase.apache.org/book.html#os

{noformat}
2.2.3. Loopback IP

HBase expects the loopback IP address to be 127.0.0.1. Ubuntu and some other 
distributions, for example, will default to 127.0.1.1 and this will cause 
problems for you.

/etc/hosts should look something like this:

127.0.0.1 localhost
127.0.0.1 ubuntu.ubuntu-domain ubuntu
{noformat}

nkeywal, thank you for reference and quick response! 
You made me curious :) So, I've looked into sources and found that some 
services start on 'localhost' and some on 'ubuntu' (accordingly to your 
example) domain name. 
I'll try to look into sources more deeply and create a patch if it's possible.
