This approach seems fairly brittle. For example whitespace in a
parameter can have unexpected results.
Given the use of a distinct preprocessor, are there any existing ones
that make sense?
Does the pig language support literals with whitespace, carriage-
returns and so on? If so, how does one define a parameter in a file
with such characters in them?
How does this approach compare to solutions used in SQL?
In Hadoop, the discussion would be in a jira. Does moving the
discussion to a jira make sense?
