Hari Sankar Sivarama Subramaniyan updated HIVE-5336:
----------------------------------------------------
Attachment: HIVE-5336.1.patch.txt
Added code change to re-align the columns after HCatSchema.remove(). Also added
a unit test case.
> HCatSchema.remove(HCatFieldSchema hcatFieldSchema) should renumber the
> fieldPositionMap and the fieldPositionMap should not be cached by the end user
> ------------------------------------------------------------------------------------------------------------------------------------------------------

> HCatSchema.remove currently does not renumber the fieldPositionMap which can
> be a problem when there are interleaving append() and remove() calls.
> 1. We should document that fieldPositionMap should not be cached by the
> end-user
> 2. We should make sure that the fieldPositionMap gets renumbered after
> remove() because HcatSchema.get will otherwise return wrong FieldSchemas.
