Summary: Fix false positive test
ql.io.parquet.TestHiveSchemaConverter.testMap
Key: HIVE-18554
URL: https://issues.apache.org/jira/browse/HIVE-18554
Project: Hive
Issue Type: Bug
Reporter: Adam Szita
Assignee: Adam Szita
In test case {{testMap}} the AssertEquals check was returning a false positive
result, due to a Parquet bug:
Original types were not asserted in equals method, this has been fixed here:
[https://github.com/apache/parquet-mr/commit/878ebcd0bc2592fa9d5dda01117c07bc3c40bb33]
What this test would produce after the Parquet fix is this:
{code:java}
expected:<message hive_schema {
optional group mapCol (MAP) {
repeated group map (MAP_KEY_VALUE) {
required binary key;
optional binary value;
}
}
}
> but was:<message hive_schema {
optional group mapCol (MAP) {
repeated group map (MAP_KEY_VALUE) {
required binary key (UTF8);
optional binary value (UTF8);
}
}
}
>{code}
Once we upgrade to a Parquet lib with this fix in place our test case will
produce failure too, hence I propose fixing it now.
