Subject [jira] [Updated] (HIVE-20980) Reinstate Parquet timestamp conversion between HS2 time zone and UTC
Date Tue, 04 Dec 2018 21:47:00 GMT

     [ https://issues.apache.org/jira/browse/HIVE-20980?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

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]
