> Pig shows auto-generated schema name for TOTUPLE in describe
> ------------------------------------------------------------
>
> Key: PIG-2050
> URL: https://issues.apache.org/jira/browse/PIG-2050
> Project: Pig
> Issue Type: Bug
> Components: impl
> Affects Versions: 0.8.0, 0.9.0
> Reporter: Richard Ding
> Priority: Minor
>
> Here is the use case:
> {code}
> grunt> A = load 'data' as (a0, a1, a2);
> grunt> B = foreach A generate TOTUPLE(a0, a2);
> grunt> describe B
> B: {org.apache.pig.builtin.totuple_a0_3: (a0: bytearray,a2: bytearray)}
> grunt> C = foreach B generate org.apache.pig.builtin.totuple_a0_3;
> 2011-05-06 14:38:14,635 [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR
> 1000: Error during parsing. Invalid alias: org in
> {org.apache.pig.builtin.totuple_a0_1: (a0: bytearray,a2: bytearray)}
> {code}
> The workaround is to specify a use-defined schema name:
> {code}
> grunt> A = load 'data' as (a0, a1, a2);
>
> grunt> B = foreach A generate TOTUPLE(a0, a2) as aa;
> grunt> describe B
> B: {aa: (a0: bytearray,a2: bytearray)}
> grunt> C = foreach B generate aa;
> grunt>
> {code}
