[jira] Created: (PIG-393) notations for data bag and data map are
confusing
notations for data bag and data map are confusing
-------------------------------------------------
Key: PIG-393
URL: https://issues.apache.org/jira/browse/PIG-393
Project: Pig
Issue Type: Wish
Reporter: Rong-En Fan
Priority: Minor
In Pig document, we use {} for data bag and [] for data map. While data bag is more like a collection (a list of other data) and data map is like a hash, their corresponding notation in other language like python (and hash in perl), is actually the other way around. In Python, they use [] for list and {} for map (dictionary). In perl, they use {} for hash, too. The notations in Pig is very confusing for developers who are familiar with Python/perl.

[jira] Commented: (PIG-393) notations for data bag and data map are

Alan Gates commented on PIG-393:
--------------------------------
I agree that if we were going to start over from scratch it would be better to use {} for a map and [] for a bag. But we have users out there using pig as is, and possibly writing post-pig parsers to deal with data. So I don't want to change our current output unless we have to.
