java.net.SocketException: Broken pipe

[Sharma, Avani]

I get the below error when dumping a 50G file on one of my Hadoop (0.20.2) 
clusters. It worked fine on another one though. I researched and this seems 
more like a network problem? I want to know how can I go about resolving this. 
What all should I look for on my cluster to debug this.
