Subject Re: pig + hadoop
Date Wed, 20 Apr 2011 03:28:19 GMT
oh yeah - that's what's going on.  what I do is on the machine that I run the pig script from,
I set the PIG_CONF variable to my HADOOP_HOME/conf directory and in my mapred-site.xml file
found there, I set the three variables.

I don't use environment variables when I run against a cluster.
