Summary: Intermittent failures of
RelMetadataTest#testPullUpPredicatesFromUnion2 in Windows
Key: CALCITE-4082
URL: https://issues.apache.org/jira/browse/CALCITE-4082
Project: Calcite
Issue Type: Bug

Reporter: Stamatis Zampetakis
The test fails from time to time in Windows since the order of pulled up
predicates appears to be different from one execution to the other.

[CI|https://github.com/apache/calcite/runs/789868941?check_suite_focus=true#step:4:495].
