Tim Armstrong resolved IMPALA-4581.
-----------------------------------
Resolution: Fixed
> Consider validating the time component of a timestamp that's read from Parquet
> ------------------------------------------------------------------------------
>
> Key: IMPALA-4581
> URL: https://issues.apache.org/jira/browse/IMPALA-4581
> Project: IMPALA
> Issue Type: Bug
> Components: Backend
> Affects Versions: Impala 2.8.0
> Reporter: Taras Bobrovytsky
> Priority: Major
>
> In IMPALA-4363, we decided not to validate the time component of timestamp
> because it was not clear how to handle leap seconds. This means that
> currently timestamps read from a Parquet file can look like:
> {code}
> 1995-01-01 54:34:17
> {code}
> We need to learn more about the behavior of such timestamp values and figure
> out if they might cause a crash.
