If you are sure that there are yarn related jars in the jars directory, try to
use --conf spark.yarn.jars=hdfs://namenode:8020/spark-3/jars/*

What do you mean "without conversion"?
def flatten(rdd: RDD[NestedStructure]): Dataset[MyCaseClass] = {
rdd.flatMap { nestedElement => flatten(nestedElement) /**
List[MyCaseClass] */ }
.toDS()
}
Can it be better?

Wouldn't toDS() do this without conversion?

Hi!
I'm trying to understand the cost of RDD to Dataset conversion
It takes me 60 minutes to create RDD [MyCaseClass] with 500.000.000.000
records
It takes around 15 minutes to convert them to Dataset[MyCaseClass]
The shema of MyCaseClass is
str01: String,
str02: String,
str03: String,
str04: Strin
Is there anyway to make the spark process visible via Spark UI when
running Spark 3.0 on a Hadoop yarn cluster? The spark documentation
talked about replacing Spark UI with the spark history server, but
didn't give much details. Therefore I would assume it is still possible
to use Spark UI wh
I've been trying to set up the latest stable version of Spark 3.0 on a

always got an error of org.apache.spark.deploy.yarn.ExecutorLauncher not

There is a multilayer perceptron implementation in Spark ML, but
that's not what you're looking for.
To parallelize model training developed using standard libraries like
Keras, use Horovod from Uber.

Hi Mukhtaj,
Parallelization on Spark is abstracted on the DataFrame.
You can run anything locally on the driver but to make it run in parallel on
the cluster you'll need to use the DataFrame abstraction.
You may want to check maxpumperla/elephas.

Dear Spark User
I am trying to parallelize the CNN (convolutional neural network) model
using spark. I have developed the model using python and Keras library. The
model works fine on a single machine but when we try on multiple machines,
the execution time remains the same as sequential.
