does Pig sit on every node in cluster or just namenode??? Please help
Hi all,
I have successfully installed pig on the machine which serves as the
namenode/master node. The only problem is when I run pig in hadoop mode it
only makes use of the namenode to perform tasks and not the whole cluster.
I tried including the hadoop/conf directory of all nodes (7) in the
HADOOPDIR variable but tha didn't work.please help. Thanks

Perhaps you've forgotten to set the PIG_CLASSPATH variable?

How are you invoking the pig query ? When you say it makes use of only the namenode, does it mean that it is running in local mode ?Or do you mean the namedone also a datanode and it is using only that datanode?
