[SPARK-9809] Task crashes because the internal accumulators are not properly initialized

When a stage failed and another stage was resubmitted with only part of partitions to compute, all the tasks failed with error message: java.util.NoSuchElementException: key not found: peakExecutionMemory.
This is because the internal accumulators are not properly initialized for this stage while other codes assume the internal accumulators always exist.
