-----------------------------------
Summary: 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
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.
