----------------------------------
Summary: Enforce a "Spill Maximum" per query
Key: HIVE-20791
URL: https://issues.apache.org/jira/browse/HIVE-20791
Project: Hive
Issue Type: New Feature
Components: Configuration
Reporter: Peter Ebert
Currently one query that spills excessively to disk can use up all cluster
space and cause other queries/workloads to fail. I understand that a global
maximum would be difficult to track, but some limit per mapper/reducer would
help keep the spill under control.
