[jira] [Created] (HIVE-14695) Enable query output size quotas as a gaurdrail for adhoc queries

--------------------------------

             Summary: Enable query output size quotas as a gaurdrail for adhoc queries
                 Key: HIVE-14695
                 URL: https://issues.apache.org/jira/browse/HIVE-14695
             Project: Hive
          Issue Type: Improvement
          Components: Hive
            Reporter: Ravi Teja


In multi tenant environments, there is a usecase of adhoc - user queries on the system besides the regular production queries.

As a gaurdrail to prevent a rogue user/job filling up the disk, we need a mechanism to limit the output data size per query level.

The strict mode works only on partitioned tables, but for the scenarios like un-partitioned tables, it doesn't work.

We can set a quota for the scratch dir generated for each query with this config.
