took a quick look, agree with shivaram's observations, you've got to handle 
`shuffleIdToMapStage` which will not be so easy.

@Ngone51 Thanks for the question. I am not quite sure of actual 
implementation of Triemap but i see

https://www.scala-lang.org/api/2.12.3/scala/collection/concurrent/TrieMap.html

https://stackoverflow.com/questions/45566633/whats-the-difference-between-scala-triemap-and-java-concurrenthashmap

https://stackoverflow.com/questions/29499381/what-is-a-triemap-and-what-is-its-advantages-disadvantages-compared-to-a-hashmap
 and conclude trieMap is better for concurrent scenarios.

but i measure the performance of ConcurrentHashMap vs TrieMap with basic 
put and get operation, it seems TrieMap is slower than ConcurrentHashmap

@squito is the master of DAGSchedulerSuite, and can provide you the best 
advice on changing or adding to the existing DAGSchedulerSuite. I'll be back 
from skiing next week and try to find some time to look at this. Hopefully 
@kayousterhout can find some time too.

@AjithShetty2489 I'm not sure just changing these two maps is sufficient ? 
For example createResultStage could in turn create all the parent stages and 
the parents stages could be ShuffleMapStage which in turn means that the map 
`shuffleIdToMapStage` would need to be protected and we'll also need to ensure 
that the MapOutputTracker `registerShuffle` is thread safe

For UT, i see DAGSchedulerSuite currently does not have same behaviour as 
DAGScheduler as its events posted to DAGSchedulerEventProcessLoopTester are 
running in same thread unlike DAGScheduler where posted events are processed in 
separate thread . Can i modify this.? or write a separate suite.? Pls suggest
