---------------------------------------
Summary: Better error instead of NPE when timestamp is null for
any row when ingesting to druid
Key: HIVE-20698
URL: https://issues.apache.org/jira/browse/HIVE-20698
Project: Hive
Issue Type: Improvement
Components: Druid integration
Reporter: Nishant Bangarwa
Assignee: Nishant Bangarwa
Currently when ingesting data to druid we get a wierd NPE when timestamp is
null for any row.
We should provide an error with a better message which helps user to know what
is actually wrong.
