macros don't accept references to items within tuples as arguments
------------------------------------------------------------------
Key: PIG-2378
URL: https://issues.apache.org/jira/browse/PIG-2378
Project: Pig
Issue Type: Improvement
Affects Versions: 0.9.1
Reporter: Joseph Adler
I'd like to be able to pass a reference to an item within a parameter to a Pig
Macro.
For example, suppose that I had a relation A with the schema A:{id:long,
header:(time:long, type:chararray)}. I'd like to call a macro by typing:
B = MY_MACRO(A, header.time);
but this does not currently work. Obviously, I could define a new relation as a
workaround, for example I could use some pig code like
AA = FOREACH a GENERATE *, header.time as time;
B = MY_MACRO(AA, time);
But that's ugly and clunky
