Summary
-------
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> d = foreach b generate flatten(outlinks.target);
gives the error shown below:
ERROR 1000: Error during parsing. Invalid alias: target in {t: (target:
chararray,text: chararray)}
org.apache.pig.impl.logicalLayer.FrontendException: ERROR 1000: Error during
