https://github.com/apache/spark/pull/16989
As @mridulm mentioned, in `HighlyCompressedMapStatus` it can be configured
in two respects:
>1. minimum size before we consider something a large block.
>2. The fraction '2' should also be configurable.
I spent quite a while for thinking this and didn't come up with good names
for these two configurations. @mridulm @cloud-fan Could you please give some
advice ? How about `spark.shuffle.accurate.block.bound`,
`spark.shuffle.accurate.block.multiples` - Actually, I think they are not good
:-(
Should I put it in this pr or make another one ?
