pyspark - AWS EMR 集群中的权限被拒绝 : user=zeppelin while using %spark. pyspark 解释器

Question

我已经创建了 pyspark 结构化流程序并尝试在 Zeppelin 笔记本中执行:

%spark.pyspark 

query_window = windowedCounts \ 
                 .writeStream \ 
                 .outputMode("complete") \ 
                 .format("memory") \ 
                 .queryName("myTable_window") \ 
                 .start() 

我收到以下错误:

Py4JJavaError: An error occurred while calling o191.start.
: org.apache.hadoop.security.AccessControlException: Permission denied: user=zeppelin, access=WRITE, inode="/mnt/tmp/temporary-e0cf0f09-a6f4-44d6-9a72-324660085608/metadata":hdfs:hadoop:drwxr-xr-x

我在 AWS EMR 集群中使用 Zeppelin Notebook 版本 0.7.1。

非常感谢您的帮助。

Answer 1

writeStream 查询似乎正在尝试将 checkpointLocation 写入云 HDFS，而 zeppelin 在写入云 HDFS 时出现问题。

通过将检查点位置添加到 S3 上的某个位置可以解决该问题。

query_window = windowedCounts \ 
            .writeStream \
            .outputMode("complete") \
            .format("memory") \
            .queryName("myTable_window") \
            .option("checkpointLocation","path_on_s3") \
            .start()
