推荐答案

在EMR主节点上:

cd /usr/lib/spark/jars
sudo wget https://repo1.maven.org/maven2/com/databricks/spark-xml_2.11/0.9.0/spark-xml_2.11-0.9.0.jar

请确保根据您的Spark版本和 https://中提供的准则选择正确的jar.github.com/databricks/spark-xml .

Make sure to select the correct jar according to your Spark version and the guidelines provided in https://github.com/databricks/spark-xml.

然后，启动Jupyter笔记本，您应该能够运行以下内容:

Then, launch your Jupyter notebook and you should be able to run the following:

df = spark.read.format('com.databricks.spark.xml').options(rootTag='objects').options(rowTag='object').load("s3://bucket-name/sample.xml")
