Apache Spark reassigned SPARK-24296:
------------------------------------
Assignee: Apache Spark
> Support replicating blocks larger than 2 GB
> -------------------------------------------
>
> Key: SPARK-24296
> URL: https://issues.apache.org/jira/browse/SPARK-24296
> Project: Spark
> Issue Type: Sub-task
> Components: Block Manager, Spark Core
> Affects Versions: 2.3.0
> Reporter: Imran Rashid
> Assignee: Apache Spark
> Priority: Major
>
> Replicating blocks send the entire block data in one frame. This results in
> a failure on the receiving end for blocks larger than 2GB.
> We should change block replication to send the block data as a stream when
> the block is large (building on the network changes in SPARK-6237). This can
> use the conf spark.maxRemoteBlockSizeFetchToMem to decided when to replicate
> as a stream, the same as we do for fetching shuffle blocks and fetching
> remote RDD blocks.
