I followed this run the whole script, but same with vscode, it's not showing anything...it's like my execution just stuck after one warning msg: 23/12/29 15:44:07 WARN ResolveWriteToStream: spark.sql.adaptive.enabled is not supported in streaming DataFrames/Datasets and will be disabled... May I know why?

Sir I have project base on spark i.e. real time wether forcast using spark streaming.

So how can I start this project.

pratibhakoli

# Start streaming defining the necessary configurations
streamingQuery = (counts
.writeStream
.format("console")
.outputMode("complete")
.trigger(processingTime="1 second")
.option("checkpointLocation", checkpointDir)
.start())
step is not executing as there is an issue with starting the streaming query .there is checkpoint directory in C drive and The specific error code "exitCode=-1073741515" indicates a problem with the Hadoop file system permissions.Could you please make any suggestion?
