      Work Description: virajjasani opened a new pull request #3855:
URL: https://github.com/apache/hadoop/pull/3855


   ### Description of PR
   DistributedCache has been deprecated long back and it's still being used as 
of today. However, all the alternative Job APIs (for deprecated 
DistributedCache APIs) still internally use DistributedCache APIs only, this is 
a deadlock and it leaves no room for removal of DistributedCache APIs in 
future. We should move core logic to Job or JobContext as required and let 
deprecated DistributedCache APIs point to the right alternatives internally.
