-----------------------------
Summary: [Java] Add UINT type test in integration to avoid
potential overflow
Key: ARROW-6218
URL: https://issues.apache.org/jira/browse/ARROW-6218
Project: Apache Arrow
Issue Type: Test
Components: Java
Reporter: Ji Liu
Assignee: Ji Liu
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.
