Spark on tin boxes like Google Dataproc or AWS EC2 often utilise YARN
resource manager. YARN is the most widely used resource manager not just
for Spark but for other artefacts as well. On-premise YARN is used
extensively. In Cloud it is also used widely in Infrastructure as a Service
such as

Hi all,
I am learning about the performance difference of Spark when performing a
JOIN problem on Serverless (K8S) and Serverful (Traditional server)
environments.
Through experiment, Spark on K8s tends to run slower than Serverful.
Through understanding the architecture, I know that Spark runs

Hello,
when you said your pandas Dataframe has 10 rows, does that mean it contains
10 images? Because if that's the case, then you'd want ro only use 3 layers

Best regards,
Adrian

i have panda dataframe with column 'image' using numpy.ndarray. shape is (500,
333, 3) per image. my panda dataframe has 10 rows, thus, shape is (10, 500,
333, 3)
when using spark.createDataframe(panda_dataframe, schema), i need to specify
the schema,
schema = StructType([
There is no such method in Spark. I think that's some EMR-specific
modification.
