Tim Armstrong created IMPALA-5622:
-------------------------------------
Summary: Ensure test coverage for spilling disabled for all
spilling operators
Key: IMPALA-5622
URL: https://issues.apache.org/jira/browse/IMPALA-5622
Project: IMPALA
Issue Type: Test
Components: Infrastructure
Reporter: Tim Armstrong
Assignee: Tim Armstrong
We should ensure that we have test coverage for disabling spilling. There are
two dimensions. I don't think we need coverage of the whole matrix, but we need
coverage along both dimensions.
Query operators:
* Agg - NOT COVERED
* Hash join - NOT COVERED (although will be with IMPALA-5570)
* Sort - covered by TestScratchLimit and TestScratchDir
* Analytic - NOT COVERED
Means of disabling:
* scratch_limit = 0 - covered by TestScratchLimit
* disable_unsafe_spills = true + a table missing stats - NOT COVERED
* starting up with no scratch disks - covered by TestScratchDir
