Hi, When I run a giraph program, it hangs there forever with output like: 14/04/02 10:16:43 INFO zookeeper.ClientCnxn: Opening socket connection to server compute-0-16.local/10.1.255.238:22181.

The input is only a common graph with 1000 lines and 800kB size. But the program runs without problem for small graph and returns expected results. What are the possible reasons? Thanks! Best Regards, Suijian
