Prasanth Jayachandran commented on ORC-370:
-------------------------------------------
This patch requires new storage-api release HIVE-19726 that removes the kryo
workaround.
> ORC PPD evaluation for date should use DateWritable
> ---------------------------------------------------
>
> Key: ORC-370
> URL: https://issues.apache.org/jira/browse/ORC-370
> Project: ORC
> Issue Type: Bug
> Affects Versions: 1.4.4, 1.5.1
> Reporter: Prasanth Jayachandran
> Assignee: Prasanth Jayachandran
> Priority: Blocker
>
> ORC PPD evaluation for Date type uses java.sql.Date for min/max comparison
> causing incorrect results.
> Date.compareTo uses millis offset which can return incorrect results
> depending on the timezone.
> Running the testcase in HIVE-19726 passed in Los Angeles but failed in Paris
> as Date.compareTo return 0 for Los Angeles but returned -1 for Paris.
> Similar to bloomfilter, min/max evaluation should use DateWritable (as
> DateWritable.compareTo uses days offset).
