Subject [GitHub] spark issue #16989: [SPARK-19659] Fetch big blocks to disk when shuffle-read...
Date Thu, 11 May 2017 00:58:42 GMT
Github user jinxing64 commented on the issue:
    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 ?
