----------------------------------
Summary: current_timestamp function
Key: SPARK-8193
URL: https://issues.apache.org/jira/browse/SPARK-8193
Project: Spark
Issue Type: Sub-task
Reporter: Reynold Xin
current_timestamp(): timestamp
Returns the current timestamp at the start of query evaluation (as of Hive
1.2.0). All calls of current_timestamp within the same query return the same
value.
We should just replace this with a timestamp literal in the optimizer.
