问题描述
看起来我再次陷入了使用spark提交运行打包的spark应用程序jar的问题.以下是我的pom文件:

以下是一个简单的代码片段，可从s3位置获取数据并打印:
def getS3Data(path: String): Map[String, Any] = {
println("spark session start.........")
val spark = getSparkSession()
val configTxt = spark.sparkContext.textFile(path)
.collect().reduce(_ + _)
val mapper = new ObjectMapper
mapper.registerModule(DefaultScalaModule)
mapper.readValue(configTxt, classOf[Map[String, String]])
}
当我从intellij运行它时，一切正常.日志很清楚，看起来不错.但是，当我使用mvn软件包对其进行打包并尝试使用spark提交运行它时，最终在.collect.reduce(_ + _)处收到以下错误.以下是我遇到的错误:
"main" java.lang.NoSuchMethodError: org.apache.hadoop.conf.Configuration.reloadExistingConfigurations()V

at java.lang.Class.forName0(Native Method)
at java.lang.Class.forName(Class.java:348)
...
我不了解未打包哪个依赖项，或者可能是问题所在，因为我确实正确设置了版本，期望hadoop的aws应该拥有所有的版本.
任何帮助将不胜感激.
解决方案
hadoop和AWS JDK之间的依赖关系非常敏感，您应该坚持使用构建hadoop依赖关系版本的正确版本.
您需要解决的第一个问题是选择一个版本的Hadoop.我看到您正在混合版本2.8.3和2.8.0.
当我查看org.apache.hadoop:hadoop-aws:2.8.0的依赖关系树时，我发现它是根据AWS开发工具包的1.10.6版本(与hadoop-aws:2.8.3相同)构建的.
这可能是导致不匹配的原因(您正在混合使用不兼容的版本).所以:
- 选择要使用的hadoop版本
- 包括
hadoop-aws并具有与您的hadoop兼容的版本 - 删除其他依赖项，或仅将它们包含在与您的hadoop版本兼容的版本中.
It looks like I am again stuck on the running a packaged spark app jar using spark submit. Following is my pom file:

Following is a simple snippet of code which fetches data from s3 location and prints it:
def getS3Data(path: String): Map[String, Any] = {
println("spark session start.........")
val spark = getSparkSession()
val configTxt = spark.sparkContext.textFile(path)
.collect().reduce(_ + _)
val mapper = new ObjectMapper
mapper.registerModule(DefaultScalaModule)
mapper.readValue(configTxt, classOf[Map[String, String]])
}
When I run it from intellij, everything works fine. the log is clear and looks good. However, when I package it using mvn package and try to run it using spark submit, I end up getting the following error at the .collect.reduce(_ + _). Following is the error I encounter:
"main" java.lang.NoSuchMethodError: org.apache.hadoop.conf.Configuration.reloadExistingConfigurations()V
at org.apache.hadoop.fs.s3a.S3AFileSystem.addDeprecatedKeys(S3AFileSystem.java:181)

I am not understanding which dependency was not packaged or what might be the issue as I did set the versions correctly expecting the hadoop aws should have all of them.
Any help will be appreciated.
解决方案
The dependencies between hadoop and AWS JDK are very sensitive, and you should stick to using the correct versions that your hadoop dependency version was built with.
The first problem you need to solve is pick one version of Hadoop. I see you're mixing versions 2.8.3 and 2.8.0.
When I look at the dependency tree for org.apache.hadoop:hadoop-aws:2.8.0, I see that it is built against version 1.10.6 of the AWS SDK (same for hadoop-aws:2.8.3).
This is probably what's causing mismatches (you're mixing incompatible versions). So:
- Choose the version of hadoop you want to use
- Include
hadoop-awswith the version compatible with your hadoop - Remove other dependencies, or only include them with versions matching the one compatible with your hadoop version.
