Running a job

This guide describes how to use the spark-submit utility to run Spark jobs in the Yandex Data Processing cluster from hosts that are not part of the Yandex Data Processing cluster.

Note

You can also run jobs in the Yandex Data Processing cluster from Yandex DataSphere. For more information, see this concept.

Getting started

Create and configure a host to run jobs remotely on the Yandex Data Processing cluster:

Image version 1.4

Image version 2.0

Create a VM with Ubuntu 16.04 LTS.
To provide network access to the Yandex Data Processing cluster hosting the created VM, set up security groups for the cluster.
Connect to the VM over SSH:
```
ssh -A <username>@<VM_FQDN>
```
Copy the repository settings from any of the Yandex Data Processing cluster hosts. To do this, run a sequence of commands on the VM you created.
1. Copy the repository address:
```
ssh root@<cluster_host_FQDN> \
"cat /etc/apt/sources.list.d/yandex-dataproc.list" | \
sudo tee /etc/apt/sources.list.d/yandex-dataproc.list
```
2. Copy the GPG key to verify Debian package signatures:
```
ssh root@<cluster_host_FQDN> \
"cat /srv/dataproc.gpg" | sudo apt-key add -
```
3. Update the repository cache:
```
sudo apt update
```
Install the required packages:
```
sudo apt install openjdk-8-jre-headless hadoop-client hadoop-hdfs spark-core spark-python
```
Note

The spark-python package is only needed to run PySpark jobs.

Copy the Hadoop and Spark configuration files:

sudo -E scp -r \
    root@<cluster_host_FQDN>:/etc/hadoop/conf/* \
    /etc/hadoop/conf/ && \
sudo -E scp -r \
    root@<cluster_host_FQDN>:/etc/spark/conf/* \
    /etc/spark/conf/

Create a user named sparkuser to run jobs under:

sudo useradd sparkuser && \
ssh root@<cluster_host_FQDN> "
  hadoop fs -mkdir /user/sparkuser
  sudo -u hdfs hdfs dfs -chown sparkuser:sparkuser /user/sparkuser
  sudo -u hdfs hdfs dfs -ls /user/sparkuser
"

Create a VM with Ubuntu 20.04 LTS.
To provide network access to the Yandex Data Processing cluster hosting the created VM, set up security groups for the cluster.
Connect to the VM over SSH:
```
ssh -A <username>@<VM_FQDN>
```
Copy the repository settings from any of the Yandex Data Processing cluster hosts. To do this, run a sequence of commands on the VM you created.
1. Copy the repository address:
```
ssh ubuntu@<cluster_host_FQDN> \
"cat /etc/apt/sources.list.d/yandex-dataproc.list" | \
sudo tee /etc/apt/sources.list.d/yandex-dataproc.list
```
2. Copy the GPG key to verify Debian package signatures:
```
ssh ubuntu@<cluster_host_FQDN> \
"cat /srv/dataproc.gpg" | sudo apt-key add -
```
3. Update the repository cache:
```
sudo apt update
```
Install the required packages:
```
sudo apt install openjdk-8-jre-headless hadoop-client hadoop-hdfs spark-core spark-python
```
Note

The spark-python package is only needed to run PySpark jobs.

Copy the Hadoop and Spark configuration files:

sudo -E scp -r \
    ubuntu@<cluster_host_FQDN>:/etc/hadoop/conf/* \
    /etc/hadoop/conf/ && \
sudo -E scp -r \
    ubuntu@<cluster_host_FQDN>:/etc/spark/conf/* \
    /etc/spark/conf/

Create a user named sparkuser to run jobs under:

sudo useradd sparkuser && \
ssh ubuntu@<cluster_host_FQDN> "
  hadoop fs -mkdir /user/sparkuser
  sudo -u hdfs hdfs dfs -chown sparkuser:sparkuser /user/sparkuser
  sudo -u hdfs hdfs dfs -ls /user/sparkuser
"

Running a job

Spark job

PySpark job

Run a job using the command:

sudo -u sparkuser spark-submit \
     --master yarn \
     --deploy-mode cluster \
     --class org.apache.spark.examples.SparkPi \
         /usr/lib/spark/examples/jars/spark-examples.jar 1000

View logs from all running containers using the yarn logs utility:

sudo -u sparkuser yarn logs \
     -applicationId application_1586176069782_0003 | grep "Pi is"

Result:

Pi is roughly 3.14164599141646

On the VM, create a file named month_stat.py with the following code:

import sys

from pyspark import SparkContext, SparkConf
from pyspark.sql import SQLContext

def main():
    conf = SparkConf().setAppName("Month Stat - Python")
    conf.set("fs.s3a.aws.credentials.provider", "org.apache.hadoop.fs.s3a.AnonymousAWSCredentialsProvider")
    sc = SparkContext(conf=conf)

    sql = SQLContext(sc)
    df = sql.read.parquet("s3a://yc-mdb-examples/dataproc/example01/set01")
    defaultFS = sc._jsc.hadoopConfiguration().get("fs.defaultFS")
    month_stat = df.groupBy("Month").count()
    month_stat.repartition(1).write.format("csv").save(defaultFS+"/tmp/month_stat")

if __name__ == "__main__":
        main()

Copy the month_stat.py file to the cluster's master host:
```
sudo -E scp month_stat.py <username>@<cluster_host_FQDN>:~/month_stat.py
```
For image 2.0, specify the ubuntu user, for image 1.4, root as the username.

Run the application:

sudo -u sparkuser spark-submit \
     --master yarn \
     --deploy-mode cluster \
     month_stat.py

The result of running the application will be exported to HDFS on the cluster. You can list the resulting files using the command:
```
ssh <username>@<cluster_host_FQDN> "hdfs dfs -ls /tmp/month_stat"
```
For image 2.0, specify the ubuntu user, for image 1.4, root as the username.

Note

You can view the job logs and search data in them using Yandex Cloud Logging. For more information, see Working with logs.
