> Time is a valid type in Iceberg but not in Hive. In Hive it is represented as a string type column, while (at least if ORC is used as underlying file format) long type is written out to data files.
> This requires translation two times: long@ORC -> LocalDate@Iceberg -> toString()@Hive and it works well for non vectorized reads, but when vectorization is turned on, we will get:
> {code:java}
> org.apache.hadoop.hive.ql.exec.vector.BytesColumnVector cannot be cast to org.apache.hadoop.hive.ql.exec.vector.LongColumnVector {code}
> Thus for now, time type is not supported with vectorization, and the relevant test cases should be ignored in such test configs.
