Hi, The Spark documentation states that "If accumulators are created with a name, they will be displayed in Spark’s UI"
http://spark.apache.org/docs/latest/programming-guide.html#accumulators Where exactly are they shown? I may be dense, but I can't find them on the UI from http://localhost:4040 :( FWIW, I'm using Spark 1.2.0, and I created the accumulators like this: val merges = sc.accumulator(0, "Merges") val vertices = sc.accumulator(0,"Vertices") Regards, Virgil.
