---------------------------------

             Summary: *Nix commands do not execute sequentially
                 Key: PIG-3477
                 URL: https://issues.apache.org/jira/browse/PIG-3477
             Project: Pig
          Issue Type: Bug
            Reporter: Keith Dsouza


Pig does not evaluate statements in sequence and evaluates the first *nix 
statement encountered first and then processes the rest of the PIG statements 
till it encounters another PIG statement which makes it hard to sequentially 
use both PIG statements as well as Unix statements useless in a sequence.

For example:

I want to read data from A and A_new_data and store it in A, I use this

LOAD A

-- Read and merge A and A.new and create A_new_data

RMF A
STORE A_new_data into A
