如何抑制在EMR上运行的spark-sql的INFO消息？

Question

我在Amazon Elastic MapReduce上运行Spark和Spark SQL中描述的在EMR上运行Spark:

本教程将指导您在Amazon EMR集群上安装和运行Spark,这是一种用于大规模数据处理的快速通用引擎.您还将使用Spark SQL在Amazon S3中创建和查询数据集,并了解如何使用Amazon CloudWatch监控Amazon EMR集群上的Spark.

我试图INFO通过编辑$HOME/spark/conf/log4j.properties来抑制日志无济于事.

输出如下:

$ ./spark/bin/spark-sql
Spark assembly has been built with Hive, including Datanucleus jars on classpath
SLF4J: Class path contains multiple SLF4J bindings.

如何压制上面的INFO消息？

Answer 1

如果您知道要禁止新EMR集群的日志记录,也可以在创建集群时添加配置选项.

EMR接受配置选项为JSON,您可以直接将其输入AWS控制台,或在使用CLI时通过文件传入.

在这种情况下,为了将日志级别更改为WARN,这里是JSON:

[
  {
    "classification": "spark-log4j",
    "properties": {"log4j.rootCategory": "WARN, console"}
  }
]

在控制台中,您将在第一个创建步骤中添加它:

或者,如果您使用CLI创建集群:

aws emr create-cluster <options here> --configurations config_file.json

您可以在EMR文档中阅读更多内容.

Answer 2

我可以通过编辑要做到这一点$HOME/spark/conf/log4j.properties是需要的,并呼吁spark-sql以--driver-java-options如下:

./spark/bin/spark-sql --driver-java-options "-Dlog4j.configuration=file:///home/hadoop/spark/conf/log4j.properties"

我可以通过添加-Dlog4j.debug选项来验证是否正在使用正确的文件:

./spark/bin/spark-sql --driver-java-options "-Dlog4j.debug -Dlog4j.configuration=file:///home/hadoop/spark/conf/log4j.properties"

Answer 3

spark-sql --driver-java-options"-Dlog4j.configuration = file:///home/hadoop/conf/log4j.properties"

cat conf/log4j.properties
