> [Zebra] Restrict schema definition for collection
> -------------------------------------------------
>
> Key: PIG-1269
> URL: https://issues.apache.org/jira/browse/PIG-1269
> Project: Pig
> Issue Type: Bug
> Reporter: Xuefu Zhang
> Assignee: Xuefu Zhang
> Fix For: 0.7.0
>
> Attachments: zebra.0302
>
>
> Currently Zebra grammar for schema definition for collection field allows
> many types of definition. To reduce complexity and remove ambiguity, and more
> importantly, to make the meta data more representative of the actual data
> instances, the grammar rules need to be changed. Only a record type is
> allowed and required for collection definition. Thus,
> fieldName:collection(record(c1:int, c2:string)) is legal, while
> fieldName:collection(c1:int, c2:string),
> fieldName:collection(f:record(c1:int, c2:string)),
> fieldName:collection(c1:int), or feildName:collection(int) is illegal.
> This will have some impact on existing Zebra M/R programs or Pig scripts that
> use Zebra. Schema acceptable in previous release now may become illegal
> because of this change. This should be clearly documented.
