hadoop - org.apache.hadoop.fs.s3native.NativeS3FileSystem 未找到

Question

在使用 MapReduce、HDFS 和 S3 配置 Hive 2 之后。我可以从 S3 查询数据，但是当我使用 JOIN 或 MAX 等 MR 操作时，Hive 会引发以下错误:

我正在尝试执行以下查询:

SELECT MAX(Column1) from table1;

我已经将 s3 和访问 key 添加到以下文件:

hdfs-site.xml

 <property> <name>fs.s3n.awsAccessKeyId</name> <value>USER</value>
 </property> 
 <property> <name>fs.s3n.awsSecretAccessKey</name>
 <value>SECRET_KEY</value> </property>

核心站点.dfs

<property>
<name>fs.s3.impl</name>
<value>org.apache.hadoop.fs.s3.S3FileSystem</value>
</property>

<property>
<name>fs.s3n.impl</name>
<value>org.apache.hadoop.fs.s3native.NativeS3FileSystem</value>
</property>

<property>
<name>fs.s3n.awsAccessKeyId</name>
<value>USER</value>
</property>
<property>
<name>fs.s3n.awsSecretAccessKey</name>
<value>SECRET_KEY</value>
</property>
</configuration>

mapred-site.xml

<property>
<name>fs.s3.impl</name>
<value>org.apache.hadoop.fs.s3.S3FileSystem</value>
</property>

<property>
<name>fs.s3n.impl</name>
<value>org.apache.hadoop.fs.s3native.NativeS3FileSystem</value>
</property>

hadoop-env.sh

export HADOOP_CLASSPATH=$HADOOP_CLASSPATH:$HADOOP_HOME/share/hadoop/tools/lib/*

hive 站点.xml

<property>
<name>fs.s3n.awsAccessKeyId</name>
<value>USER</value>
</property>
<property>
<name>fs.s3n.awsSecretAccessKey</name>

看起来 hadoop-aws 不在类路径中。它可能在工具/库中。
