Santhosh Srinivasan updated PIG-159: ------------------------------------ Patch Info: [Patch Available] Assignee: Santhosh Srinivasan (was: Alan Gates) > Make changes to the parser to support new types functionality > ------------------------------------------------------------- > > Key: PIG-159 > URL: https://issues.apache.org/jira/browse/PIG-159 > Project: Pig > Issue Type: Sub-task > Components: impl > Reporter: Alan Gates > Assignee: Santhosh Srinivasan > Attachments: parser_chages_v10.patch, parser_chages_v11.patch, > parser_chages_v12.patch, parser_chages_v13.patch, parser_chages_v5.patch, > parser_chages_v6.patch, parser_chages_v7.patch, parser_chages_v8.patch, > parser_chages_v9.patch > > > In order to support the new types functionality described in > http://wiki.apache.org/pig/PigTypesFunctionalSpec, the parse needs to change > in the following ways: > 1) AS needs to support types in addition to aliases. So where previously it > was legal to say: > a = load 'myfile' as a, b, c; > it will now also be legal to say > a = load 'myfile' as a integer, b float, c chararray; > 2) Non string constants need to be supported. This includes non-string > atomic types (integer, long, float, double) and the non-atomic types bags, > tuples, and maps. > 3) A cast operator needs to be added so that fields can be explicitly casted. > 4) Changes to DEFINE, to allow users to declare arguments and return types > for UDFs -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
