[jira] [Updated] (SPARK-37086) Fix the R test of FPGrowthModel for
Scala 2.13
[ https://issues.apache.org/jira/browse/SPARK-37086?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Kousuke Saruta updated SPARK-37086:
-----------------------------------
Description:
Similar to the issue filed in SPARK-37059, the 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, the test fails with Scala 2.13.
{code}
