Adesh Kumar Rao commented on HIVE-25323:
----------------------------------------
[~klcopp] Debugged it and figured out that the issue is happening because
vectorization is using older java libraries (`java.sql.timestamp` instead of
using `java.time.Instant/ZonedDateTime` etc) and are not considering timezones
while converting to/from timestamp. This is not the case with non-vectorized
execution anymore.
The test which is failing is comparing the result of non-vectorized execution
with vectorized execution and hence failing (because of different results). I
discussed this with [~mmccline], Fixing the tests will actually require fixing
the vectorized timestamp conversion. I will go ahead and raise a PR to comment
out the tests and create another jira for the proper fix for vectorized
execution.
