stack commented on BUILDS-4:
----------------------------
[~giridharan.kesa...@cognizant.com]
We only fail on this one host? On others we just work? I presume the hadoop
group made up of more than one host and these tests don't always fail.
When I run above little program on a few machines I get:
On mac laptop:
kalashnikov:hbase.git stack$ java Hostname
localhost/127.0.0.1
/0.0.0.0:0
On a linux machine:
[stack@c2020 ~]$ java Hostname
c2020.halxg.cloudera.com/10.20.84.26
/0.0.0.0:0
They don't fail with UnknownHostException
These tests pass most anywhere else they run.

> Project: Infra Build Platform
> Issue Type: New Feature
> Reporter: stack
>
> 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.
