Alan Gates commented on PIG-1758: --------------------------------- bq. LoadCaster interface provides methods to cast complex types – but they are silently ignored by Pig So before this patch casting of bytearray to tuple or bag fails in 0.8? That is definitely a fix worth back porting. The addition of deep casting I have a hard time thinking of as a bug since we have never it in the past. Since this is relatively small and did not work in the past I am ok with back porting it. I do think we should add something in the release notes that says the feature is experimental. I have a concern in general about when we back port features and when we do not, but I will start a thread on that on the dev list. > Deep cast of complex type > ------------------------- > > Key: PIG-1758 > URL: https://issues.apache.org/jira/browse/PIG-1758 > Project: Pig > Issue Type: New Feature > Components: impl > Affects Versions: 0.8.0 > Reporter: Daniel Dai > Assignee: Daniel Dai > Fix For: 0.9.0 > > Attachments: PIG-1758-1.patch, PIG-1758-2.patch > > > Pig does not handle deep cast from bag -> bag, tuple -> tuple. Eg, the > following script does not produce desired result: > {code} > a = load '1.txt' as (a0:bag{t:tuple(i0:double)}); > b = foreach a generate (bag{tuple(int)})a0; > dump b; > {code} > The result tuple still contain int inside tuple of bag. > PIG-613 fix the case we cast bytearray -> bag/tuple, we take complex type > including inner types, but bag->bag, tuple->tuple is still not effective. -- This message is automatically generated by JIRA.
