Purpose
fix #8642
HiveTypeUtils.HiveToPaimonTypeVisitor.atomic()mapped HivetimestamptoDataTypes.TIMESTAMP_MILLIS()(precision 3), silently truncating sub-millisecond values when a Hive schema is inferred into Paimon (migrate/clone/CREATE via Hive).DataTypes.TIMESTAMP()(default precision 6) for parity with the same-file local-zoned reverse path (TIMESTAMP_WITH_LOCAL_TIME_ZONE(), precision 6) andSparkTypeUtils.java:436(new TimestampType(), precision 6).Tests
HiveTypeUtilsTest#testToPaimonTypeTimestampPrecisionassertingtoPaimonType("timestamp")equalsDataTypes.TIMESTAMP()and its precision equals the local-zoned reverse-path precision.mvn -pl paimon-hive/paimon-hive-common -am clean install(JDK 11) — HiveTypeUtilsTest: 2 tests passed.
