[jira] [Commented] (SPARK-41013) spark-3.1.2以cluster模式提交作业报 Could not initialize class com.github.luben.zstd.ZstdOutputStream

--------------------------------------
Can you clarify the issue? this doesn't look like it directly relates to Spark, but, the error message is truncated. We need to see the underlying cause

> 但是同样的代码，以client模式提交可以正常执行。
> 以cluster模式提交作业暂时的解决办法是在spark-default.conf 中配置spark.shuffle.mapStatus.compression.codec lz4 作业可以正常提交。
> 想咨询下cluster模式，在shuffle 过程中使用zstd压缩为什么会不能正常使用呢？
> 有任何思路提供的大佬将不胜感激。
