Setup: Matlab 2014a, Mac OS x 10.7.5.
Problem: Parpool throws a Java exception when I try to run it with my home wifi turned on and works when I turn it off.
Run: parpool
Error:
Error using parpool (line 99)
Java exception occurred:
java.net.UnknownHostException: craig-2: craig-2: nodename nor servname provided, or not known
at java.net.InetAddress.getLocalHost(InetAddress.java:1438)
Caused by: java.net.UnknownHostException: craig-2: nodename nor servname provided, or not known
at java.net.Inet6AddressImpl.lookupAllHostAddr(Native Method)

at java.net.InetAddress.getAddressesFromNameService(InetAddress.java:1258)
at java.net.InetAddress.getLocalHost(InetAddress.java:1434)
Any ideas?
Thanks,
Craig

I have the same error! Maybe is related with this java but, don't you think?

Same here, matlab prompt '!hostname' and adding it to host file worked for me. Ubuntu 12.04 with R2014a x64. Thanks!

Did you find a solution for the problem? I am having the same problem with OSX 10.9.3:

I have not found a permanent solution, but the issue seems to be related to network settings. When I unplug my computer from the network and turn off WiFi, I am able to get the parallel pool to start. This is only a temporary workaround, but I hope to figure out the underlying cause with a bit more investigation.

Thanks for the suggestion Craig! I went to check the host file and noticed that my parpool is starting up fine now. The only thing that changed is that I shutdown and brought my laptop home for a few days where I used it on a different network. Very curious...
