I had the same issue.  My problem was the use of VPN
connected to work, and at the same time working
with M/R jobs on my Mac.  It occurred to me that
maybe Hadoop was binding to the wrong IP (the IP
given to you after connecting through VPN),  
bottom line, I disconnect from the VPN, and the M/R job
finished as expected after that.

This is logic because, after that you configure to connect to the VPN,
your machines have
other IPs, based on the request of the private network. You can test,
changing the IPs for the
new ones based on the VPN request.
