Daniel Dai updated PIG-730: --------------------------- Attachment: (was: PIG-730-1.patch) > problem combining schema from a union of several LOAD expressions, with a > nested bag inside the schema. > ------------------------------------------------------------------------------------------------------- > > Key: PIG-730 > URL: https://issues.apache.org/jira/browse/PIG-730 > Project: Pig > Issue Type: Bug > Environment: pig local mode > Reporter: Christopher Olston > Assignee: Daniel Dai > Fix For: 0.9.0 > > Attachments: PIG-730-1.patch > > > grunt> a = load 'foo' using BinStorage as > (url:chararray,outlinks:{t:(target:chararray,text:chararray)}); > grunt> b = union (load 'foo' using BinStorage as > (url:chararray,outlinks:{t:(target:chararray,text:chararray)})), (load 'bar' > using BinStorage as > (url:chararray,outlinks:{t:(target:chararray,text:chararray)})); > grunt> c = foreach a generate flatten(outlinks.target); > grunt> d = foreach b generate flatten(outlinks.target); > ---> Would expect both C and D to work, but only C works. D gives the error > shown below. > ---> Turns out using outlinks.t.target (instead of outlinks.target) works for > D but not for C. > ---> I don't care which one, but the same syntax should work for both! > 2009-03-24 13:15:05,376 [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR > 1000: Error during parsing.
