Comment:
your network your problem link

   * The machines are trying to communicate using IPv6. Hadoop [[HadoopIPv6|does not currently support IPv6]]
   * The host's IP address has changed but a long-lived JVM is caching the old value. This is a known problem with JVMs (search for "java negative DNS caching" for the details and solutions). The quick solution: restart the JVMs
   
- These are all network configuration/router issues. As it is your network, only you can find out and track down the problem.
