Thejas M Nair updated PIG-999:
------------------------------
Issue Type: Sub-task (was: Bug)
Parent: PIG-998
> sorting on map-value fails if map-value is not of bytearray type
> ----------------------------------------------------------------
>
> Key: PIG-999
> URL: https://issues.apache.org/jira/browse/PIG-999
> Project: Pig
> Issue Type: Sub-task
> Reporter: Thejas M Nair
>
> When query execution plan is created by pig, it assumes the type to be
> bytearray because there is no schema information associated with map fields.
> But at run time, the loader might return the actual type. This results in a
> ClassCastException.
> This issue points to the larger issue of the way pig is handling types for
> map-value.
> This issue should be fixed in the context of revisiting the frontend logic
> and pig-latin semantics.
> This is related to PIG-880 . The patch in PIG-880 changed PigStorage to
> always return bytearray for map values to work around this, but other loaders
> like BinStorage can return the actual type causing this issue.
