Apache Spark reassigned SPARK-21236:
------------------------------------
Assignee: Apache Spark
> Make the threshold of using HighlyCompressedStatus configurable.
> ----------------------------------------------------------------
>
> Key: SPARK-21236
> URL: https://issues.apache.org/jira/browse/SPARK-21236
> Project: Spark
> Issue Type: Bug
> Components: Shuffle
> Affects Versions: 2.1.1
> Reporter: jin xing
> Assignee: Apache Spark
> Priority: Minor
>
> Currently the threshold of using {{HighlyCompressedMapStatus}} is hardcoded
> 2000.
> We could make this configurable. Thus users having enough memory on driver
> can configure the threshold to be larger thus to save the size of blocks more
> accurately in {{CompressedMapStatus}}.
