----------------------------------------------
Summary: Calendar inside DATE, TIME and TIMESTAMP literals for
Calcite should have UTC timezone
Key: HIVE-15863
URL: https://issues.apache.org/jira/browse/HIVE-15863
Project: Hive
Issue Type: Bug
Components: CBO
Affects Versions: 2.2.0
Reporter: Jesus Camacho Rodriguez
Assignee: Jesus Camacho Rodriguez
Related to CALCITE-1623.
At query preparation time, Calcite uses a Calendar to hold the value of DATE,
TIME, TIMESTAMP literals. It assumes that Calendar has a UTC (GMT) time zone,
and bad things might happen if it does not. Currently, we pass the Calendar
object with user timezone from Hive. We need to pass it with UTC timezone and
make the inverse conversion when we go back from Calcite to Hive.
