Description:
Currently, If task reads data from more than one block and it is from different
read methods we ignore the second read method bytes. For example:
{noformat}
CoalescedRDD
|
Task1
/ | \
hadoop hadoop cached
{noformat}
if Task1 starts reading from the hadoop blocks first, then the input metrics
for Task1 will only contain input metrics from the hadoop blocks and ignre the
input metrics from cached blocks. We need to change the way we collect input
metrics so that it is not a single value but rather a collection of input
metrics for a task.
