I am working on a pyspark streaming job (ver 2.2.0) and I need to enable checkpointing. At high level my python script goes like this:
def doJob(self):ssc = StreamingContext.getOrCreate('<S3-location>', <function to create ssc>)
and I run it:
myJob = StreamingJob(...)myJob.doJob()
The problem is that StreamingContext.getOrCreate is not able to have access to hadoop configuration configured in the constructor and fails to load from checkpoint with
"com.amazonaws.AmazonClientException: Unable to load AWS credentials from any provider in the chain"
If I export AWS credentials to the system ENV before starting the script it works!
I see the Scala version has an option to provide the hadoop configuration that is not available in python
I don't have the whole Hadoop, just Spark, so I don't really want to configure hadoop's xmls and such
