> Currently, when reading Parquet table using Spark's `VectorizedColumnReader`,
> we hit an issue where we specify requested (projection) schema where one of
> the field's type is widened from int32 to long.
> Expectation is that since this is totally legitimate primitive type
> promotion, we should be able to read Ints into Longs w/ no problems (for ex,
> Avro is able to do that perfectly fine).
> However, we're facing an issue where `ParquetVectorUpdaterFactory.getUpdater`
> method fails w/ the exception listed below.
> Looking at the code, It actually seems to be allowing the opposite – it
> allows to "down-size" Int32s persisted in the Parquet to be read as Bytes or
> Shorts for ex. I'm actually not sure what's the rationale for this behavior,
> and this actually seems like a bug to me (as this will essentially be leading
> to data truncation):
> {code:java}
> case INT32:
> if (sparkType == DataTypes.IntegerType || canReadAsIntDecimal(descriptor,
> sparkType)) {
> return new IntegerUpdater();
> } else if (sparkType == DataTypes.LongType && isUnsignedIntTypeMatched(32))
> {
> // In `ParquetToSparkSchemaConverter`, we map parquet UINT32 to our
> LongType.
> // For unsigned int32, it stores as plain signed int32 in Parquet when
> dictionary
> // fallbacks. We read them as long values.
> return new UnsignedIntegerUpdater();
