[jira] [Comment Edited] (IMPALA-7595) Check failed:
IsValidTime(time_) at timestamp-value.h:322

------------------------------------------------------------------
I am not too surprised about hitting that DCHECK in Parquet fuzz tests, because the time_ field is not validated after memcpying TimestampValues from Parquet pages. I think that it would be reasonable to treat negative or >=24h values as invalid and replace them with NULL.
