Hello, I am seeing negative values for accumulators. Here's my implementation in a standalone app in Spark 1.1.1rc:
implicit object BigIntAccumulatorParam extends AccumulatorParam[BigInt] { def addInPlace(t1: Int, t2: BigInt) = BigInt(t1) + t2 def addInPlace(t1: BigInt, t2: BigInt) = t1 + t2 def zero(initialValue: BigInt) = BigInt(0) } val capped_numpings_accu = sc.accumulator(BigInt(0))(BigIntAccumulatorParam) myRDD.foreach(x=>{ capped_numpings_accu+=BigInt(x._1).min(threshold_var)}) When I remove the min() condition, I no longer see negative values.
