[SPARK-10543] [CORE] Peak Execution Memory Quantile should be Per-tas…
…k Basis Read `PEAK_EXECUTION_MEMORY` using `update` to get per task partial value instead of cumulative value. I tested with this workload: ```scala val size = 1000 val repetitions = 10 val data = sc.parallelize(1 to size, 5).map(x => (util.Random.nextInt(size / repetitions),util.Random.nextDouble)).toDF("key", "value") val res = data.toDF.groupBy("key").agg(sum("value")).count ``` Before: ![image](https://cloud.githubusercontent.com/assets/4317392/9828197/07dd6874-58b8-11e5-9bd9-6ba927c38b26.png) After: ![image](https://cloud.githubusercontent.com/assets/4317392/9828151/a5ddff30-58b7-11e5-8d31-eda5dc4eae79.png) Tasks view: ![image](https://cloud.githubusercontent.com/assets/4317392/9828199/17dc2b84-58b8-11e5-92a8-be89ce4d29d1.png) cc andrewor14 I appreciate if you can give feedback on this since I think you introduced display of this metric.
