Andrew Chung commented on REEF-1413:
------------------------------------

Yes, if we overwrite the file anyway, is there a reason to keep the de-allocation event?

> {{DFSEvaluatorLogOverwriteWriter}} currently reads from original EvalutorChangesLog before
overwriting it. This can become a problem when the job has been running for a long time. We
can make this more efficient by simply recording the Evaluators it expects in a log.
