UnknownHostException after upgrade from 1.0.3 > 1.1.1
Lewis John Mcgibbney 2013-01-09, 03:37
Hi All,

Over @Nutch, we are experiencing failed builds on our nightly CI builds
after the above upgrade.
This happens on the Jenkins (Solaris and Ubuntu) builds but NOT on local
operating systems. This has been verified by numerous members of the
community.
The stack we get is appended below.
So far we've located some threads [0][1][2] which display 'similar'
behaviour, however no solution is jumping out as obvious at this point in
time.
Any help would be greatly appreciated, we would like to get stable builds
back online.
Thank you very much in advance.

Lewis
