Thanks. The main problem i am having is i cant get pig to run in mapreduce/hadoop mode… Its not connecting to hadoop. When i run pig it tries to connect to hadoop but fails.

It fails like this:

Connecting to hadoop file system at: file:/// (<= this is supposed to have localhost:506493)….that was a random port number

I haven’t used Pig since shortly after this post but I imagine you can set HADOOPSITEPATH with “export HADOOPSITEPATH=/path”.

Grunt is the command line interface to pig, you can run pig commands from there. http://wiki.apache.org/pig/Grunt
