[jira] Created: (PIG-613) Casting elements inside a tuple does not
take effect
Casting elements inside a tuple does not take effect
----------------------------------------------------
Key: PIG-613
URL: https://issues.apache.org/jira/browse/PIG-613
Project: Pig
Issue Type: Bug
Components: impl
Affects Versions: types_branch
Reporter: Viraj Bhat
Fix For: types_branch
Attachments: myfloatdata.txt
Consider the following Pig script which casts return values of the SQUARE UDF which are tuples of doubles to long. The describe output of B shows it is long, however the result is still double.
{code}
register statistics.jar;
A = load 'myfloatdata.txt' using PigStorage() as (doublecol:double);
B = foreach A generate (tuple(long))statistics.SQUARE(doublecol) as squares:(loadtimesq);
describe B;
explain B;
dump B;
{code}
===========================================
Describe output of B:
B: {squares: (loadtimesq: long)}
===========================================================
Sample output of B:
((7885.44))
((792098.2200010001))
((1497360.9268889998))
((50023.7956))
((0.972196))
((0.30980356))
((9.9760144E-7))
===========================================================
Cause: The cast for Tuples has not been implemented in POCast.java

Attachment: PIG-1255-2.patch
Checked with hadoop guys. For Serializer/Deserializer, we should always open, but never close. There is another place in pig code does not follow this. Attach a new patch address both positions.

[jira] Commented: (PIG-613) Casting elements inside a tuple does
not take effect
Posted by "Richard Ding (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/PIG-613?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12837479#action_12837479 ]
Richard Ding commented on PIG-613:
----------------------------------
The patch looks good. A few comments:
* File TestTextDataParser.java should be removed.
* In LoadCaster, javadoc is needed for the new parameters.
* In Utf8StorageConverter's bytesToTuple method, the cast to Tuple can be removed. Same for the cast in bytesToBag and bytesToMap. In consumeBag method, use consumeTuple instead of consumeComplexType to be more precise. In bytesToBoolean method, use Boolean.valueof to be consistent with other existing methods. Also should the new helper methods consume{Bag, Tuple, Map} be private (not public)?
* The new methods added in impl.util.Utils class should be added to a test.util class since they are only used in the unit tests.
I maybe too picky here, but I would like to see more consistent coding style across files. For example,
* Use 4 spaces (not tab) for indentation: tabs are used in ResourceSchema. POCast, and TypeCheckingVisitor.

Here is another example:
1.txt:
(0.2,0.3)
a = load '1.txt';
b = foreach a generate (tuple(int, int))$0;
describe b;
b: {(int,int)}
dump b;
((0.2,0.3))
The expect result is ((0, 0))
