---------------------------------
Summary: Ignore time type column in Iceberg testing for vectorized
runs
Key: HIVE-25420
URL: https://issues.apache.org/jira/browse/HIVE-25420
Project: Hive
Issue Type: Bug
Reporter: Ádám Szita
Assignee: Ádám Szita
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.
