Description

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.
