A way for task preemption in Big data analytics platform

## What we have done

* a simple shell script for monitoring node's metadata (e.g. disk access, network Tx Rx etc) in a cluster

* read and write for chekcpointing data (note: checkpointRead is private in spark, we need to package function into org.apache.spark)

### We have already done some simulation about the JCT gain we can get using Benefault

The performance gain is 15-30%

### We test latency in varied scenarios

* Measure checkpoint latency using Spark

* Word Count with checkpointing

* Sorting with checkpoint

* GroupByKey with Checkpointing

* DecisionTree with periodic Checkpointing

* We now design schemes for evaluate best gain we can get using Benefault

* find sweet spot for whether kill or preempt
