Comment: Remove hive.parquet.mr.int96.enable.utc.write.zone as the jira has been reverted.

...

Current Hive implementation of Parquet stores timestamps in UTC on-file, this flag allows skipping of the conversion on reading Parquet files created from other tools that may not have done so.

hive.parquet.mr.int96.enable.utc.write.zone
  • Default Value: false
  • Added In: Hive 2.4.0 with HIVE-12767
