Daryn Sharp commented on HDFS-2960:
-----------------------------------
Trying to stub out dns was one of the very first things I tried to do when I
joined the project. I had wildcard dns causing tests to fail with excruciating
delays because {{IPC.Client}} has a hardcoded 45 retries for
{{SocketTimeoutException}}. I think it will take JNDI which is where I gave up.
PS. What's even funnier is how the tests pound on the *real* foo.com!
