auto_assign_roles

auto_assign_roles(cluster_name)

Automatically assign roles to hosts and create the roles for all the services in a cluster.

Assignments are done based on services and hosts in the cluster, and hardware specifications. If no hosts are added to the cluster, an exception will be thrown preventing any role assignments. Existing roles will be taken into account and their assignments will be not be modified.

Available since API v6.

auto_configure

auto_configure(cluster_name)

Automatically configures roles and services in a cluster.

Overwrites some existing configurations. Might create new role config groups. Only default role config groups must exist before calling this endpoint. Other role config groups must not exist. If they do, an exception will be thrown preventing any configuration. Ignores the Cloudera Management Service even if colocated with roles of this cluster. To avoid over-committing the heap on hosts, assign hosts to this cluster that are not being used by the Cloudera Management Service.

Available since API v6.

Returns the properties of the provided ozone bucket if the bucket exists.

from pprint import pprint
# Configure HTTP basic authorization: basic
configuration = cm_client.Configuration()
configuration.username = 'YOUR_USERNAME'

get_ozone_s3_gateway_info

ApiOzoneS3GatewayInfo get_ozone_s3_gateway_info(cluster_name, bucket_name=bucket_name)

Returns the REST url for the Ozone S3 Gateway, as well as the AWS credentials needed to access the S3 endpoint. Additionally, creates a bucket with the specified name under the volume s3v. If no Ozone is present, or Ozone is not running, returns success with an empty response. Currently, we get the credentials for the Hive kerberos principal, and give ownership of the created bucket to the same. This is likely not a permanent solution. If the cluster is not kerberizied, we return dummy credentials. Requires CDH 7.2.1+ or CDH 7.1.3+

rolling_upgrade

ApiCommand rolling_upgrade(cluster_name, body=body)

Command to do a rolling upgrade of specific services in the given cluster This command does not handle any services that don't support rolling upgrades. The command will throw an error and not start if upgrade of any such service is requested. This command does not upgrade the full CDH Cluster. You should normally use the upgradeCDH Command for upgrading the cluster. This is primarily helpful if you need to need to recover from an upgrade failure or for advanced users to script an alternative to the upgradeCdhCommand. This command expects the binaries to be available on hosts and activated. It does not change any binaries on the hosts.

Example

from __future__ import print_function

import cm_client
from cm_client.rest import ApiException
from pprint import pprint
# Configure HTTP basic authorization: basic
configuration = cm_client.Configuration()
configuration.username = 'YOUR_USERNAME'
configuration.password = 'YOUR_PASSWORD'

# create an instance of the API class
api_instance = cm_client.ClustersResourceApi(cm_client.ApiClient(configuration))
cluster_name = 'cluster_name_example' # str | The name of the cluster.
body = cm_client.ApiRollingUpgradeServicesArgs() # ApiRollingUpgradeServicesArgs | Arguments for the rolling upgrade command. (optional)

update_cluster

ApiCluster update_cluster(cluster_name, body=body)

Update an existing cluster.

To update the CDH version, provide the new value in the "fullVersion" property. Setting a correct version that matches the actual installed software will ensure the correct version-specific features, such as services, roles, commands, and configurations. This need not be manually set for clusters using parcels. In general this action is only necessary after the CDH packages have been manually updated. Note that a downgrade may be rejected if it would render existing services or roles unusable. For major upgrade, the "upgradeService" cluster command should be used instead.

To rename the cluster, provide the new name in the "displayName" property for API >= 6, or in the "name" property for API <=5.

Available since API v2.

Example

from __future__ import print_function
import time
import cm_client
from cm_client.rest import ApiException
from pprint import pprint
# Configure HTTP basic authorization: basic
configuration = cm_client.Configuration()
configuration.username = 'YOUR_USERNAME'
configuration.password = 'YOUR_PASSWORD'

# create an instance of the API class
api_instance = cm_client.ClustersResourceApi(cm_client.ApiClient(configuration))
cluster_name = 'cluster_name_example' # str | The name of the cluster.
body = cm_client.ApiCluster() # ApiCluster |  (optional)

try:
    api_response = api_instance.update_cluster(cluster_name, body=body)

upgrade_cdh_command

ApiCommand upgrade_cdh_command(cluster_name, body=body)

Perform CDH upgrade to the specified version.

Allows the following upgrades:

• Major upgrades from any CDH 4 to any CDH 5
• Minor upgrades from any CDH 5 to any CDH 5
• Maintenance upgrades or downgrades (a.b.x to a.b.y)

If using packages, CDH packages on all hosts of the cluster must be manually upgraded before this command is issued.

The command will upgrade the services and their configuration to the version available in the CDH5 distribution.

Unless rolling upgrade options are provided, the entire cluster will experience downtime. If rolling upgrade options are provided, command will do a "best-effort" rolling upgrade of the given cluster, i.e. it does plain upgrade of services that cannot be rolling upgraded, followed by first rolling upgrading non-slaves and then rolling restarting the slave roles of services that can be rolling restarted. The slave restarts are done host-by-host.

Available since v9. Rolling upgrade is only available with Cloudera Manager Enterprise Edition. A more limited upgrade variant available since v6.

Example

from __future__ import print_function
import time
import cm_client
from cm_client.rest import ApiException
from pprint import pprint
# Configure HTTP basic authorization: basic
configuration = cm_client.Configuration()
configuration.username = 'YOUR_USERNAME'
configuration.password = 'YOUR_PASSWORD'

# create an instance of the API class
api_instance = cm_client.ClustersResourceApi(cm_client.ApiClient(configuration))
cluster_name = 'cluster_name_example' # str | The name of the cluster.
body = cm_client.ApiCdhUpgradeArgs() # ApiCdhUpgradeArgs | Arguments for the command. See ApiCdhUpgradeArgs. (optional)

    api_response = api_instance.upgrade_cdh_command(cluster_name, body=body)

upgrade_services_command

ApiCommand upgrade_services_command(cluster_name)

Upgrades the services in the cluster to the CDH5 version.

This command requires that the CDH packages in the hosts used by the cluster be upgraded to CDH5 before this command is issued. Once issued, this command will stop all running services before proceeding.

If parcels are used instead of CDH system packages then the following steps need to happen in order:

1. Stop all services manually
2. Activate parcel
3. Run this upgrade command

Example

from __future__ import print_function
import time
import cm_client
from cm_client.rest import ApiException
from pprint import pprint
# Configure HTTP basic authorization: basic
configuration = cm_client.Configuration()
configuration.username = 'YOUR_USERNAME'
configuration.password = 'YOUR_PASSWORD'

# create an instance of the API class
api_instance = cm_client.ClustersResourceApi(cm_client.ApiClient(configuration))
cluster_name = 'cluster_name_example' # str | The name of the cluster.

try:
    api_response = api_instance.upgrade_services_command(cluster_name)
