Question

我使用qubole / streamx作为kafka接收器连接器来使用kafka中的数据并将它们存储在AWS S3中。我在AIM中创建了一个用户，权限为AmazonS3FullAccess。然后在hdfs-site.xml中设置密钥ID和密钥，在quickstart-s3.properties中分配dir。

配置如下：

quickstart-s3.properties：

name=s3-sink
connector.class=com.qubole.streamx.s3.S3SinkConnector
format.class=com.qubole.streamx.SourceFormat
tasks.max=1
topics=test
flush.size=3
s3.url=s3://myemrbuckettest/raw_data
hadoop.conf.dir=/data/java/streamx/resource/hadoop-conf

HDFS-site.xml中：

<property>
    <name>fs.s3.awsAccessKeyId</name>
    <value>BALABALABALA</value>
  </property>
  <property>
    <name>fs.s3.awsSecretAccessKey</name>
    <value>balabalabala</value>

使用connect-standalone ./connect-standalone.properties ./quickstart-s3.properties启动接收器时会出现此错误。

我使用的地区是cn-north-1。需要在hdfs-site.xml中指定区域信息，如下所示，否则默认情况下将连接到s3.amazonaws.cn。

<property>
    <name>fs.s3a.access.key</name>
    <value>BALABALABALA</value>
  </property>
  <property>
    <name>fs.s3a.secret.key</name>
    <value>balabalabalabala</value>
  </property>
  <property>
    <name>fs.s3.impl</name>
    <value>org.apache.hadoop.fs.s3a.S3AFileSystem</value>
    <!--value>org.apache.hadoop.fs.s3native.NativeS3FileSystem</value-->
  </property>
  <property>
    <name>fs.s3a.endpoint</name>
    <value>s3.cn-north-1.amazonaws.com.cn</value>connect-standalone ./connect-standalone.properties ./quickstart-s3.properties
  </property>
