Littlestar updated SPARK-6239: ------------------------------ Description: Spark MLlib fpm#FPGrowth minSupport should use long instead ============== val minCount = math.ceil(minSupport * count).toLong because: 1. [count]numbers of datasets is not kown before read. 2. [minSupport ]double precision. from mahout#FPGrowthDriver.java addOption("minSupport", "s", "(Optional) The minimum number of times a co-occurrence must be present." + " Default Value: 3", "3"); I just want to set minCount=2 for test. Thanks. was: Spark MLlib fpm#FPGrowth minSupport should use double instead ============== val minCount = math.ceil(minSupport * count).toLong because: 1.
