Joey Echeverria commented on PIG-2456:
--------------------------------------

The idea is to add a new file that contains pig statements that are always 
executed. This is more akin to the .hiverc in Hive 
(https://issues.apache.org/jira/browse/HIVE-1414) than the pig.properties or 
.pigrc files that already exists. My use case would be to pre-define a bunch of 
UDFs:

REGISTER /usr/lib/pig/contrib/piggybank/java/piggybank.jar;
DEFINE SequenceFileLoader org.apache.pig.piggybank.storage.SequenceFileLoader();
...

I could also see it being useful to put in common LOAD statements so that you 
can just start working with the data from grunt.

I tried setting the file variable in .pigrc and pig.properties, but it didn't 
seem to cause the file to be loaded.

This is somewhat related to macros where I want a default file that is always 
imported.
