> 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.
