--------------------------------------
Summary: Fix the R test of FPGrowthModel for Scala 2.13
Key: SPARK-37086
URL: https://issues.apache.org/jira/browse/SPARK-37086
Project: Spark
Issue Type: Bug
Components: ML, R, Tests
Affects Versions: 3.3.0
Reporter: Kousuke Saruta
Assignee: Kousuke Saruta
Similar to the issue filed in SPARK-37059, an R test of FPGrowthModel assumes
that the result records returned by FPGrowthModel.freqItemsets are sorted by a
certain kind of order but it's wrong.
As a result, such tests fail with Scala 2.13.
