Reynold Xin updated SPARK-8861:
-------------------------------
Description:
The basic metric can be the number of tuples that is flowing through. We can
add more metrics later.
In order for this to work, we can add a new "accumulators" method to SparkPlan
that defines the list of accumulators, .e.g.
{code}
def accumulators: Map[String, Accumulator]
{code}
was:The basic metric can be the number of tuples that is flowing through. We
