Karen Coppage updated HIVE-20980:
---------------------------------
Description: With HIVE-20007, Parquet timestamps became timezone-agnostic.
This means that timestamps written after the change are read exactly as they
were written; but timestamps stored before this change are effectively
converted from the writing HS2 server time zone to GMT time zone. This patch
reinstates the original behavior: timestamps are converted to UTC before write
and from UTC before read. (was: [WIP]
