下面对 4 节点集群中每个节点上的 /etc/dse/spark/hive-site.xml 进行了更改。

<property>
  <name>fs.s3.awsAccessKeyId</name>
  <value>****</value>
</property>

<property>
  <name>fs.s3.awsSecretAccessKey</name>
  <value>****</value>
</property>

<property>
  <name>fs.s3n.awsAccessKeyId</name>
  <value>****</value>
</property>

<property>
  <name>fs.s3n.awsSecretAccessKey</name>
  <value>****</value>
</property>

<property>
  <name>fs.s3a.awsAccessKeyId</name>
  <value>****</value>
</property>

<property>
  <name>fs.s3a.awsSecretAccessKey</name>
  <value>****</value>
</property>

在运行 spark thrift 服务器和 spark-beeline 客户端的节点上设置以下 ENV 变量 export AWS_SECRET_ACCESS_KEY=****
export AWS_ACCESS_KEY_ID=*****

启动 Spark thrift 服务器，如下所示

dse -u cassandra -p ***** spark-sql-thriftserver start --conf spark.cores.max=2 --conf spark.executor.memory=2G --conf 
spark.driver.maxResultSize=1G --conf spark.kryoserializer.buffer.max=512M --conf spark.sql.thriftServer.incrementalCollect=true

使用 S3 存储桶从 Spark Beeline 创建了一个表作为源

dse -u cassandra -p ***** spark-beeline --total-executor-cores 2 --executor-memory 2G 
The log file is at /home/ubuntu/.spark-beeline.log
Beeline version 1.2.1.2_dse_spark by Apache Hive
beeline> !connect jdbc:hive2://localhost:10000 cassandra

ROW FORMAT DELIMITED FIELDS TERMINATED BY ',' LOCATION 's3a://hive-getsimpl/test';

我收到以下错误

Error: org.apache.spark.sql.execution.QueryExecutionException: FAILED:           
Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask.MetaException (message:com.amazonaws.services.s3.model.AmazonS3Exception:

注意：AWS 密钥是有效的，并且一直在使用其他 python 脚本

s3a 使用的配置名称不同；你需要设置fs.s3a.access.key和fs.s3a.secret.key。不要触摸环境变量，因为它们只会增加混乱。
