> During [REEF-80], we discovered that the Driver today keeps a log of all Evaluator (de-)allocations on HDFS for use during a Driver restart situation. This is happening even for Drivers that don't make use of the Driver restart feature. We should refactor this code to be modular, not to impose this cost on all Drivers.
