> May I ask you to run a maven build as well? Just to be in the safe side... I am not 100% sure but as you changed the exclusion in `SparkBuild.scala` but not in a pom.xml we might find something here. > And agree, I think you need Maven exclusions to match SBT @attilapiros @srowen In SPARK-35134 (https://github.com/apache/spark/pull/32230), there is a netty version conflict problem, the phenomenon that triggers the bug is that even if we use `netty-4.1.51-all.jar`, there will be `copying deps/jars/netty-handler-4.1.50.Final.jar -> pyspark-3.2.0.dev0/deps/jars` and `copying deps/jars/netty-transport-native-epoll-4.1.50.Final.jar -> pyspark-3.2.0.dev0/deps/jars` behavior during sbt testing. So I add 2 new `ExclusionRule` in SPARK-35134 to fix this sbt test bug. ``` ExclusionRule("io.netty", "netty-handler"), ExclusionRule("io.netty", "netty-transport-native-epoll") ``` We didn't find this problem during Maven testing, so I didn't make corresponding change for Maven In SPARK-35134. Then after Netty-4.1.69 ([Netty#11732 netty-all should not re-package jars](https://github.com/netty/netty/pull/11732)) , netty-all replaces a fat jar with separate modules, keeping `ExclusionRule("io.netty", "netty-handler")` and `ExclusionRule("io.netty", "netty-transport-native-epoll")` will result in the absence of `netty-transport-native-epoll-4.1.71.Final.jar` and `netty-handler-4.1.71.Final.jar` in the during sbt test because `netty-all-4.1.71.jar` no longer contains them. -- This is an automated message from the Apache Git Service.
