--------------------------------
Summary: Separate connection timeout and idle timeout for shuffle
Key: SPARK-31199
URL: https://issues.apache.org/jira/browse/SPARK-31199
Project: Spark
Issue Type: Improvement
Components: Shuffle
Affects Versions: 3.1.0
Reporter: runnings
spark.shuffle.io.connectionTimeout only used for connection timeout for
connection setup while spark.shuffle.io.idleTimeout is used to control how long
to kill the connection if it seems to be
idle([#27963|https://github.com/apache/spark/pull/27963])
These 2 timeouts could be quite different and shorten connectiontimeout could
help fast fail the shuffle task in some cases
