Question

我已经向bluemix spark提交了一个python作为服务，它已经失败了。不幸的是，日志记录不足，并不能让我知道它失败的原因。

如何增加日志级别输出？

火花作为服务的输出：

我已成功针对BigInsights群集运行相同的作业。在biginsights集群上运行时，我也会得到更详细的输出。

Answer 1

从群集下载stderr-%timestamp%和stdout-%timestamp%个文件到您运行spark-submit.sh的本地目录。通常，您会在这两个文件中找到工作问题。

参考：http://spark.apache.org/docs/latest/spark-standalone.html#monitoring-and-logging

如何在bluemix上增加spark-submit作业的日志输出？
