Thejas M Nair updated PIG-544:

    Attachment: PIG-544.txt

- DataReaderWriter bytestoX logic for complex datatypes  re-factored into 
separate functions in same class and used by BinStorage.
- Utf8StorageConverter logs warning and returns null if type conversions fail.
- Moved logging utility functions from org.apache.pig.tools.grunt.Utils to 
org.apache.pig.impl.util.LogUtils. Updated files that used grunt.Utils .
- Added unit test cases for type conversion failures in TestEvalPipeline2 .

> Utf8StorageConverter.java does not always produce NULLs when data is malformed

> It does so for scalar types but not for complext types and not for the fields 
> inside of the complext types.
> This is because it uses different code to parse scalar types by themselves 
> and scalar types inside of a complex type. It should really use the same (its 
> own code to do so.)
> The code it is currently uses, is inside of TextDataParser.jjt and is also 
> used to parse constants so we need to be careful if we want to make changes 
> to it.
