Spark submit fails on Kubernetes (EKS) with "invalid null input: name" - docker

Question

I am trying to run spark sample SparkPi docker image on EKS. My Spark version is 3.0.
I created spark serviceaccount and role binding. When I submit the job, there is error below:
2020-07-05T12:19:40.862635502Z Exception in thread "main" java.io.IOException: failure to login

The docker image is created using OOTB dockerfile provided in Spark installation.
docker build -t spark:latest -f kubernetes/dockerfiles/spark/Dockerfile .
What am I doing wrong here? Please help.
SOLUTION
Finally it worked out after I comment the below line from docker file.
USER ${spark_uid}
Though, now, container is running as root but at least it is working.

Answer 1

I had the same problem. I solved it by changing the k8s job.
Hadoop is failing to find a username for the user. You can see the problem by running whoami in the container, which yields whoami: cannot find name for user ID 185. The spark image entrypoint.sh contains code to add the user to /etc/passwd, which sets a username. However command bypasses the entrypoint.sh, so instead you should use args like so:
containers:
- name: spark-pi
image: <registry>/spark-pi-3.0
args: [
"/bin/sh",
"-c",
"/opt/spark/bin/spark-submit \
--master k8s://https://10.100.0.1:443 \
--deploy-mode cluster ..."
]

Answer 2

Seems like you are missing the ServiceAccount/AWS role credentials so that your job can connect to the EKS cluster.
I recommend you set up fine-grained IAM roles for service accounts.
Basically, you would have something like this (after you set up the roles in AWS):
apiVersion: v1
kind: ServiceAccount
metadata:
annotations:
eks.amazonaws.com/role-arn: arn:aws:iam::123456789012:role/my-serviceaccount-Role1
name: spark
namespace: helios
Then your job would look something like this:
apiVersion: batch/v1
kind: Job
metadata:
name: spark-pi
namespace: helios
spec:
template:
spec:
containers:
- name: spark-pi
image: <registry>/spark-pi-3.0
command: [
"/bin/sh",
"-c",
"/opt/spark/bin/spark-submit \
--master k8s://https://<EKS_API_SERVER> \
--deploy-mode cluster \
--name spark-pi \
--class org.apache.spark.examples.SparkPi \
--conf spark.kubernetes.namespace=helios
--conf spark.executor.instances=2 \
--conf spark.executor.memory=2G \
--conf spark.executor.cores=2 \
--conf spark.kubernetes.container.image=<registry>/spark-pi-3.0 \
--conf spark.kubernetes.container.image.pullPolicy=Always \
--conf spark.kubernetes.authenticate.driver.serviceAccountName=spark \
--conf spark.jars.ivy=/tmp/.ivy
local:///opt/spark/examples/jars/spark-examples_2.11-2.4.0.jar" ]
env:
- name: AWS_ROLE_ARN
value: arn:aws:iam::123456789012:role/my-serviceaccount-Role1
- name: AWS_WEB_IDENTITY_TOKEN_FILE
value: /var/run/secrets/eks.amazonaws.com/serviceaccount/token
volumeMounts:
- mountPath: /var/run/secrets/eks.amazonaws.com/serviceaccount
name: aws-iam-token
readOnly: true
serviceAccountName: spark
restartPolicy: Never

Answer 3

I had the same problem. I solved it by adding into submit container
export SPARK_USER=spark3
without comment line USER ${spark_uid}

Answer 4

Finally it worked out after I comment the below line from docker file.
USER ${spark_uid}
Though, now, container is running as root but at least it is working.

Answer 5

I ran into the same issue and was able to resolve it by specifying runAsUser on the pod spec without having to modify the spark docker image.
securityContext:
runAsUser: 65534
runAsGroup: 65534

Answer 6

I had the same issue, fixed it by adding
RUN echo 1000:x:1000:0:anonymous uid:/opt/spark:/bin/false >> /etc/passwd
line in the last part Spark Dockerfile
RUN echo '1000:x:1000:0:anonymous uid:/opt/spark:/bin/false' >> /etc/passwd
ENTRYPOINT [ "/opt/entrypoint.sh" ]
# Specify the User that the actual main process will run as
USER ${spark_uid}
so full dockerfile looks like this
cat spark-3.2.0-bin-hadoop3.2/kubernetes/dockerfiles/spark/Dockerfile
