apache-spark - PySpark 修复/删除控制台进度条

Question

如下所示，Spark 控制台输出进度条弄乱了输出。是否有可用于关闭舞台进度条的配置或标志？或者更好的是，如何修复控制台日志，以便在阶段完成后进度条消失？这可能只是 PySpark 的一个错误，但我不确定。

有时甚至会更糟(向右滚动):

Answer 1

您可以通过设置禁用

spark.ui.showConsoleProgress = 错误

或者

在 log4j.properties 中降低日志记录级别高于INFO ，即到 ERROR

相关 Spark jiras:

https://issues.apache.org/jira/browse/SPARK-4017

https://issues.apache.org/jira/browse/SPARK-18719

spark.ui.showConsoleProgress自 1.2 版以来一直在 Spark 中，但只会在 Spark 2.2 中记录。

示例代码:

spark.conf.set('spark.ui.showConsoleProgress', False)
