---------------------------------------------
Summary: TestBuilder.baselineRecords(List<Map) doesn't handle null well
Key: DRILL-3570
URL: https://issues.apache.org/jira/browse/DRILL-3570
Project: Apache Drill
Issue Type: Bug
Components: Tools, Build & Test
Reporter: Daniel Barclay (Drill)
Assignee: Jason Altekruse
TestBuilder.baselineRecords(List<Map>) accepts a call with null (doesn't reject it with a bad-parameter error) but does not accept it as an specification of a baseline (to prevent the "Must provide some kind of baseline, either a baseline file or another query" error).
Either it should reject null (and the parameter documentation should probably have "; not null" added), or when it gets null, it should take that as providing some kind of baseline (maybe a baseline of zero rows (like and empty list), or maybe a don't-care baseline) (and the documentation should reflect that).
