I am in process of installing and learning pig. I have a hadoop cluster and
when I try to run pig it errors out:
Hadoop version is Hadoop 0.20.2-cdh3u2,
and pig version is pig-0.8.1-cdh3u3
I download the pig from Cloudera using sudo yum install hadoop-pig.
When I try to run it I get the following error:
