Subject [jira] Commented: (PIG-944) Zebra schema is taken from Pig through TableStorer's construct
Date Thu, 10 Sep 2009 00:15:57 GMT

    [ https://issues.apache.org/jira/browse/PIG-944?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12753339#action_12753339

Yan Zhou commented on PIG-944:

The previously attached patch is based upon some new features under development and consequently
might not be applicable to the trunk. I'm going to attahc another patch shortly based upon
version 1 branch.

In addition to the problem in TableOutputFormat.checkOutputSpecs, the SchemaConverter.toPigSchema
 did not convert the Zebra schema to Pig's properly if nested types are involved: the low
level column schemas were simply missing.
Also, the conversion from Pig to Zebra schema is just missing beyond a hack to work on specially
prefixed column names.

> It should be from StoreConfig in TableOutputFormat.checkOutputSpecs method because the
information is dynamic in Pig's execution engine and should not be taking a static argument
to the constructor.
