I have created pyspark structured streaming program and trying to execute in the Zeppelin notebook:
%spark.pyspark
query_window = windowedCounts \
.writeStream \
.outputMode("complete") \
.format("memory") \
.queryName("myTable_window") \
.start()
I am getting the following error:
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
I am using the Zeppelin Notebook Version 0.7.1 in AWS EMR cluster.
Help would be much appreciated.
Full stacktrace:

it appears that the writeStream query is attempting the write the checkpointLocation to the cloud HDFS and zeppelin has issues with writing to the cloud HDFS.
by adding the checkpoint location to somewhere on S3 solves the issue.
query_window = windowedCounts \
.writeStream \
.outputMode("complete") \
.format("memory") \
.queryName("myTable_window") \
.option("checkpointLocation","path_on_s3") \
.start()
