> The data stored today in ATSv2 is either system data in that it is generated by YARN, or custom data that is generated by Application Masters themselves.
> Data retention policy is necessary to maintain feature parity between the new MR JHS with the current JHS.
> We may want to provide separate policies for system data and custom data.
