各个dataproc火花日志在哪里? [英] where are the individual dataproc spark logs?

问题描述

dataproc spark作业日志位于何处?我知道在日志记录"部分下有来自驱动程序的日志，但是执行节点呢?另外，Spark正在执行的详细步骤记录在哪里(我知道我可以在Application Master中看到它们)?我正在尝试调试似乎挂起的脚本，并且似乎冻结了火花.

Where are the dataproc spark job logs located? I know there are logs from the driver under "Logging" section but what about the execution nodes? Also, where are the detailed steps that Spark is executing logged (I know I can see them in the Application Master)? I am attempting to debug a script that seems to hang and spark seems to freeze.

推荐答案

任务日志存储在/tmp下的每个工作节点上.

The task logs are stored on each worker node under /tmp.

可以通过纱线记录汇总将它们收集在一个地方.在集群创建时设置这些属性(通过带有yarn:前缀的--properties):

It is possible to collect them in one place via yarn log aggregation. Set these properties at cluster creation time (via --properties with yarn: prefix):

• yarn.log-aggregation-enable=true
• yarn.nodemanager.remote-app-log-dir=gs://${LOG_BUCKET}/logs
• yarn.log-aggregation.retain-seconds=-1

• yarn.log-aggregation-enable=true
• yarn.nodemanager.remote-app-log-dir=gs://${LOG_BUCKET}/logs
• yarn.log-aggregation.retain-seconds=-1
