> Make rpc timeout and retry for shuffle registration configurable
> ----------------------------------------------------------------
>
> Key: SPARK-20640
> URL: https://issues.apache.org/jira/browse/SPARK-20640
> Project: Spark
> Issue Type: Bug
> Components: Shuffle
> Affects Versions: 2.0.2
> Reporter: Sital Kedia
> Fix For: 2.3.0
>
>
> Currently the shuffle service registration timeout and retry has been
> hardcoded (see
> https://github.com/sitalkedia/spark/blob/master/network/shuffle/src/main/java/org/apache/spark/network/shuffle/ExternalShuffleClient.java#L144
> and
> https://github.com/sitalkedia/spark/blob/master/core/src/main/scala/org/apache/spark/storage/BlockManager.scala#L197).
> This works well for small workloads but under heavy workload when the
> shuffle service is busy transferring large amount of data we see significant
> delay in responding to the registration request, as a result we often see the
> executors fail to register with the shuffle service, eventually failing the
> job. We need to make these two parameters configurable.
