A list of common Docker on YARN related problem and how to resolve them.

Install Yarn On Docker Board

Docker is not enabled

Problem statement
Started an application on Docker, but the containers are running as regular containers.
Root cause
Docker is not enabled.
Resolution
Enable Docker in Cloudera Manager.

YARN_CONTAINER_RUNTIME_TYPE runtime environment variable is not provided during Application submission

Problem statement
Started an application on Docker, but the containers are running as regular containers.
Root cause
YARN_CONTAINER_RUNTIME_TYPE runtime environment variable is not provided during Application submission.
Resolution
Provide the environment variable when submitting the application.

LCE enforces running user to be nobody in an unsecure cluster

Problem statement
On an unsecure cluster, Appattempt exited with exitCode -1000 with diagnostic message:
Root cause
LCE enforces running user to be nobody in an unsecure cluster if yarn.nodemanager.linux-container-executor.nonsecure-mode.limit-users is set.
Resolution

In Cloudera Manager, add the following configuration to the YARN Service Advanced Configuration Snippet (Safety Valve) for yarn-site.xml safety-valve by clicking the plus icon:

  • Key: yarn.nodemanager.linux-container-executor.nonsecure-mode.limit-users
  • Value: false
Then use a user who has the correct permissions or add more permissive access to these folders for the nobody user. For more information, see YARN force nobody user on all jobs.

The Docker binary is not found

Problem Statement
Container launch fails with the following message:
Root cause
The Docker binary is not found.
Resolution
The Docker binary is either not installed or installed to a different folder. Install Docker binary and provide the path to the binaries by specifying it using the Docker Binary Path (docker.binary) property in Cloudera Manager.

The Docker daemon is not running or does not respond

Problem statement
Container launch fails with the following message:
Root cause
The Docker daemon is not running or does not respond.
Resolution
Start or restart the Docker daemon with the dockerd command.

Docker rpm misses some symbolic link

Problem statement
On Centos 7.5 container launch fails with the following message:
Root cause
Docker rpm misses some symbolic link.
Resolution
Create the missing symbolic link using the following command in a terminal:sudo ln -s /usr/libexec/docker/docker-runc-current /usr/bin/docker-runc

YARN_CONTAINER_RUNTIME_DOCKER_IMAGE is not set

Problem statement
Container launch fails with the following message:
Root cause
YARN_CONTAINER_RUNTIME_DOCKER_IMAGE is not set.
Resolution
Set the YARN_CONTAINER_RUNTIME_DOCKER_IMAGE environment variable when submitting the application.

Image is not trusted

Problem statement
Container launch fails with the following message:
Root cause
The image is not trusted.
Resolution
Add the image’s registry to the list of trusted registries (docker.trusted.registries). For example in case of library/ubuntu:latest, add the “library” registry to that list.

Docker image does not include the Snappy library

Problem statement
Running the hadoop-mapreduce-examples pi job fails with the following error:
Root cause
The provided Docker image does not include the Snappy library. MapReduce needs this if compression is used and the Snappy codec is chosen for compression.
Resolution
Either add the Snappy library to the image or change the “Compression Codec of MapReduce Map Output” to some other codec

Hadoop UserGroupInformation class does not have access to the user permissions in the host system

Problem statement
Container fails shortly after start with the following exception:
Root cause
The Hadoop UserGroupInformation class does not have access to the user permissions in the host system.
Resolution
Mount the /etc/passwd to the image. More configuration issues can be found in upstream Hadoop 3.2 documentation: Launching Applications Using Docker Containers upstream documentation.

Problem Statement
MapReduce and Spark jobs fail with Docker on a secure cluster. It cannot get Kerberos realm.
Root cause
Kerberos configuration is not mounted for Docker containers.
Download
Resolution
In case of MapReduce job, add the following environment variable when running the job: -Dmapreduce.reduce.env=YARN_CONTAINER_RUNTIME_DOCKER_MOUNTS=/etc/krb5.conf:/etc/krb5.conf:ro

Ensure to add /etc/krb5.conf to the Allowed Read-Only Mounts in Cloudera Manager configuration.

In case of Spark job, ensure that mount is added as read-only for /etc/krb5.conf as spark.appMasterEnv and spark.executorEnv:

The ssl-client.xml file and the truststore file is not mounted for Docker containers using MapReduce

Problem statement
Reducer cannot connect to the shuffle service due to SSL handshake issues.
NodeManager logs:
Root cause
For normal containers, the file ssl-client.xml defines the SSL settings and it is on the classpath (normally under directory: /etc/hadoop/conf.cloudera.YARN-1/ssl-client.xml). Therefore, it has to be mounted for Docker containers using MapReduce. Since the ssl-client.xml file refers to the truststore file as well, that also had to be mounted.
Resolution

Yarn Install Docker Slow

Add the following when running the job:

Ensure to add /etc/hadoop/conf.cloudera.YARN-1/ssl-client.xml and /var/lib/cloudera-scm-agent/agent-cert/cm-auto-global_truststore.jks to the Allowed Read-Only Mounts in Cloudera Manager.

Note, that the location of the truststore can vary, so verify its location from the ssl-client.xml file. You can access that file in Clouder Manager through the Processes view for NodeManager.
