> Project: Apache Arrow

> As per discussion [https://github.com/apache/arrow/pull/5002]
> For UINT type, when write/read json data in integration test, it extend data
> type(i.e. Long->BigInteger, Int->Long) to avoid potential overflow.
> Like UINT8 the write side and read side code like this:
>
> {code:java}
> case UINT8:
> generator.writeNumber(UInt8Vector.getNoOverflow(buffer, index));
> break;{code}
>
> {code:java}
> BigInteger value = parser.getBigIntegerValue();
> buf.writeLong(value.longValue());
> {code}
> Should add a test to avoid potential overflow in the data transfer process.
