stack commented on BUILDS-4:
----------------------------

java.net.UnknownHostException: asf901.ygridcore.net: asf901.ygridcore.net

Anything interesting if you run this program

{code}
import java.net.InetAddress;
import java.net.InetSocketAddress;
public class Hostname {
  public static void main(final String [] args) {
    try {
      System.out.println(InetAddress.getLocalHost());
      System.out.println((new InetSocketAddress("0.0.0.0", 0)));
    } catch (Throwable t) {
      throw new RuntimeException(t);
    }
  }
}
{code}

I see one of our tests fails just doing InetAddress.getLocalHost();

It comes back with:
{code}
java.net.UnknownHostException: asf901.ygridcore.net: asf901.ygridcore.net
        at java.net.InetAddress.getLocalHost(InetAddress.java:1473)
        at 
org.apache.hadoop.hbase.master.TestClockSkewDetection.testClockSkewDetection(TestClockSkewDetection.java:93)
{code}

Thanks.

Something is wonky in resolve.

> Some of our tests are failing because they fail to resolve a host.
> The way the test works is it puts up an rpc server then asks the socket what 
> its address is, passes the address in same process for use by a client and it 
> fails UnknownHostException.  A few tests fail this way.  Anything INFRA can 
> do to fix the host resolve?
> Thanks.
