Explicitly setting host name in /etc/hosts on Solaris slave(s)
Hi Builds@,
In both Nutch builds [0][1] we're currently experiencing a problem where
Hadoop related tests fail with the following Exception
> java.net.UnknownHostException: -s: -s
>From what I have gathered the "-s" output implies that some Linux-specific
script was run as root on your Solaris machine and did a "hostname -s",
which on Linux prints the short hostname, but on Solaris sets the current
hostname of the machine to "-s".
I've been advised that a reboot will clear up that problem (however I know
it is not possible for me to do this).
So the option is to ensure that the build machine's hostname is present in
the /etc/hosts file. As I cannot view the existing file, is there a
suggested way to do this via a shell script pre-build?
Any suggestions would be greatly appreciated.
Thank you
Lewis

Hi Gav,
Thanks for the reply.
I'll give the builds a spin and see where we are.

Thanks for pointing out that our Hudson slave instance had root access.
Whoever did that wants shooting.
Removed that level of access so it should not be possible to happen again.
Hostname reset.
Now to find who ran the script as sudo in the first place.
Thanks
