权限被拒绝：在AWS EMR集群中使用％spark.pyspark解释器时，user = zeppelin

我创建了pyspark结构化流媒体程序并尝试在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 Version 0.7.1。

非常感谢帮助。

似乎writeStream查询正在尝试将checkpointLocation写入云HDFS，并且zeppelin在写入云HDFS时遇到问题。

通过将检查点位置添加到S3上的某个位置来解决问题。 

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

我也遇到了这个问题，您的文件系统不允许writeStream在指定的文件位置写入数据，这就是“权限被拒绝”的原因。 添加检查点位置HDFS或S3。

query = lines \
.writeStream \
.format("console") \
.option("checkpointLocation","s3://S3_bucket/test") \
.start()

希望这会有所帮助。
