Travis Woodruff updated PIG-3650:
---------------------------------
Attachment: PIG-3650.patch
Adding patch to fix. Iterates over all fieldSchemas (removes the Math.min) and
adds padding to the tuple (as requested PIG-3100) as needed within that loop.
Added new test to reproduce this issue.
Updated imcomplete data test to verify that null padding still works in this
case,
> Fix for PIG-3100 breaks column pruning
> --------------------------------------
>
> Key: PIG-3650
> URL: https://issues.apache.org/jira/browse/PIG-3650
> Project: Pig
> Issue Type: Bug
> Affects Versions: 0.12.0, 0.12.1
> Reporter: Travis Woodruff
> Priority: Critical
> Attachments: PIG-3650.patch
>
>
> The fix for PIG-3100 does {{Math.min(fieldSchemas.length, tup.size())}} in
> {{PigStorage.applySchema()}}. This means that if column pruning is in use,
> all schema columns will not be iterated over (since tup.size() will be less
> than fieldSchemas.length) and the schema will not be applied to all columns,
