GH-655: Failure in UnionReader.read after DecimalVector promotion to UnionVector#656lidavidm merged 5 commits intoapache:mainfrom

…o UnionVector (apache#61) When a DecimalVector is promoted to a UnionVector via a PromotableWriter, the UnionVector will have the decimal vector in it's internal struct vector, but the decimalVector field will not be set. If UnionReader.read is then used to read from the UnionVector, it will fail when it tries to read one of the promoted decimal values, due to decimalVector being null, and the exact decimal type not being provided. This failure is unnecessary though as we have a pre-existing decimal vector, the caller just does not know the exact type - and it shouldn't be required to. The change here is to check for a pre-existing decimal vector in the internal struct when getDecimalVector() is called. If one exists, set the decimalVector field and return. Otherwise, if none exists, throw the exception.

There was a problem hiding this comment.
Should we apply to only child, or also on parameterized types ?

I'm not sure, I'm submitting a change someone else made in our repo. Would it be any different if used the parameterized type instead?
