一、问题描述

在运行某个Pyspark代码时报错如下：

Warning: Ignoring non-Spark config property: deploy-mode
Setting default log level to "WARN".
To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use setLogLevel(newLevel).

二、解决方案

上面是因为在yarn上执行spark作业时，其他的app占用了集群资源，导致新的job无法使用足够的资源，可以Kill掉相应的job再试试：

lsof -i:4041
lsof -i:4042
kill -9 进程id

查了下其他的说法：spark-shell里面又单独的设置了spark的context，因为spark-shell里已经有一个context对象了，所以新建创建的数据无法使用。
