本文介绍了spark-1.4.1 saveAsTextFile 到 S3 在 emr-4.0.0 上非常慢的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我在 amazom aws emr 4.0.0 中运行 spark 1.4.1

I run spark 1.4.1 in amazom aws emr 4.0.0

由于某些原因，与 emr 3.8 相比，emr 4.0.0 上的 saveAsTextFile 速度非常慢(原为 5 秒，现在为 95 秒)

For some reson spark saveAsTextFile is very slow on emr 4.0.0 in comparison to emr 3.8 (was 5 sec, now 95 sec)

实际上 saveAsTextFile 说它是在 4.356 秒内完成的，但在那之后我看到很多 INFO 消息，在接下来的 90 秒内来自 com.amazonaws.latency 记录器的 404 错误

Actually saveAsTextFile says that it's done in 4.356 sec but after that I see lots of INFO messages with 404 error from com.amazonaws.latency logger for next 90 sec

spark> sc.parallelize(List.range(0, 1600000),160).map(x => x + "	" + "A"*100).saveAsTextFile("s3n://foo-bar/tmp/test40_20")

推荐答案

为了解决这个问题，我按照 Neil Jonkers 在 user@spark.apache.org 上的建议向 mapred-site.xml 添加了以下设置

To solve the problem I added the following settings to mapred-site.xml as suggested by Neil Jonkers on user@spark.apache.org

<property>
  <name>mapred.output.direct.EmrFileSystem</name>
  <value>true</value>
</property>
<property>
  <name>mapred.output.direct.NativeS3FileSystem</name>
  <value>true</value>
</property>

可以通过在 aws 命令中添加以下内容来完成

It can be done by adding the following to aws command

classification=mapred-site,properties=[mapred.output.direct.EmrFileSystem=true,mapred.output.direct.NativeS3FileSystem=true]

或者通过在配置json文件中添加以下内容

or by adding the following to configuration json file

  {
    "Classification": "mapred-site",
    "Properties": {
      "mapred.output.direct.EmrFileSystem": "true",
      "mapred.output.direct.NativeS3FileSystem": "true"
    }
  }
