> Have a single shared network timeout in Spark
> ---------------------------------------------
>
> Key: SPARK-4688
> URL: https://issues.apache.org/jira/browse/SPARK-4688
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Reporter: Patrick Wendell
> Priority: Critical
>
> We have several different timeouts, but in most cases users just want to set
> something that is large enough that they can avoid GC pauses. We should have
> a single conf "spark.network.timeout" that is used as the default timeout for
> all network interactions. This can replace the following timeouts:
> {code}
> spark.core.connection.ack.wait.timeout
> spark.akka.timeout
> spark.storage.blockManagerSlaveTimeoutMs (undocumented)
> spark.shuffle.io.connectionTimeout (undocumented)
> {code}
> Of course, for compatibility we should respect the old ones when they are
> set. This idea was proposed originally by [~rxin] and I'm paraphrasing his
> suggestion here.
