Spark Master在提交工作节点应用程序/作业的IOException之后无休止地重新提交

Question

我对火花世界很陌生。在我们的应用程序中，我们有一个内置的Spark独立集群（版本2.4.3)，它通过Spark提交主URL接收由主数据引擎加载器应用程序提交的作业。

我们在不同的VM上有3个工作从节点。有趣的是，由于一些IOException，我以一种非常有限和神秘的格式发布，以限制系统内部。Master假设它需要一次又一次地向同一个员工重新提交相同的作业/申请（数千次中的10次）

我的查询是：我们没有修改spark.deploy.MaxExecutorRetries，所以它应该是默认的10。

此错误或重复提交是否受到此参数的影响，或者我们需要检查此问题的另一个配置，以防Spark master无法识别辅助作业失败。

Answer 1

尝试在配置下面设置

spark.task.maxFailures = 2
