-----------------------------------
Summary: Split hive.strict.checks.large.query into two configs,
enable partition filter check by default
Key: HIVE-18552
URL: https://issues.apache.org/jira/browse/HIVE-18552
Project: Hive
Issue Type: Improvement
Components: Hive
Reporter: Sahil Takiar
{{hive.strict.checks.large.query}} controls the strict checks for restricting
order bys with no limits, and scans of a partitioned table without a filter on
the partition table.
While both checks prevent "large" queries from being run, they both control
very different behavior. It would be better if users could control these
restrictions separately.
Furthermore, many users make the mistake of abusing partitioned tables and
often end up in a situation where they are running queries that are doing
full-table scans of partitioned tables. This can lead to lots of issues for
Hive - e.g. OOM issues because so many partitions are loaded in memory. So it
would be good if we enabled this restriction by default.
