Key: HIVE-2378
URL: https://issues.apache.org/jira/browse/HIVE-2378
Project: Hive
Issue Type: Improvement
Reporter: Kevin Wilfong
Assignee: Kevin Wilfong
When a bigint is implicitly cast to a double (when a bigint is involved in an
equality expression with a string or double) precision may be lost, resulting
in unexpected behavior. Until we fix the underlying issue we should throw an
error in strict mode, and a warning in nonstrict mode alerting the user about
this.
