Xiangrui Meng updated SPARK-8872:
---------------------------------
Description: In `FPGrowthSuite`, we only tested output with minSupport 0.5,
where the expected output is hard-coded. We can add equivalent R code using the
arules package to generate the expect output for validation purpose, similar to
https://github.com/apache/spark/blob/master/mllib/src/test/scala/org/apache/spark/ml/regression/LinearRegressionSuite.scala#L98
and the test code in https://github.com/apache/spark/pull/7005. (was: In
