Cheng Lian created PARQUET-379:
----------------------------------
Summary: PrimitiveType.union erases original type
Key: PARQUET-379
URL: https://issues.apache.org/jira/browse/PARQUET-379
Project: Parquet
Issue Type: Bug
Components: parquet-mr
Affects Versions: 1.8.0, 1.7.0, 1.6.0, 1.5.0
Reporter: Cheng Lian
The following test case
{code}
test("merge primitive types") {
val expected =
Types.buildMessage()
.addField(
Types
.required(INT32)
.as(DECIMAL)
.precision(9)
.scale(0)
.named("f"))
.named("root")
assert(expected.union(expected) === expected)
}
{code}
produces the following assertion error
{noformat}
message root {
required int32 f;
}
did not equal message root {
required int32 f (DECIMAL(9,0));
}
{noformat}
This is because {{PrimitiveType.union}} doesn't handle original type properly.
An open question is that, can two primitive types with the same primitive type
name but different original types be unioned?
