Subject [jira] Commented: (PIG-1256) [Zebra] Bag field should always contain a tuple type as the field schema in ResourceSchema object converted from Zebra Schema
Date Wed, 24 Feb 2010 18:59:28 GMT

    [ https://issues.apache.org/jira/browse/PIG-1256?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12837951#action_12837951
] 

Xuefu Zhang commented on PIG-1256:
----------------------------------

1. All test case failure seemed due to env issues. Manually running the failed cases succeeds.
2. In this patch, schemas for a collection field such as f:collection(f1:int, f2:string) and
f:collection(record(f1:int, f2:string)) are treated as the same by both Zebra and by PIG when
they are converted to Pig ResourceSchema and later in Pig to Pig schema. Previously when Zebra
schema is directly converted to Pig schema, the second case has no second level access in
Pig script. Now both the cases has second level access.

> Pig now requires that schema converted from Zebra Schema contains Tuple type as field
schema in .7 release. Zebra needs to take care of all cases where Record is not explicitly
specified.
