Overview

The Apache Mahout project's goal is to build an environment for quickly creating scalable, performant machine learning applications. Learn more at mahout.apache.org.

This charm deploys version 0.13.0 of the Mahout component from Apache Bigtop.

Deploying

This charm requires Juju 2.0 or greater. If Juju is not yet set up, please follow the getting-started instructions prior to deploying this charm.

This charm is intended to be used with one of the apache bigtop bundles. For example:

juju deploy hadoop-processing

This will deploy an Apache Bigtop Hadoop cluster. More information about this deployment can be found in the bundle readme.

Now add Mahout and relate it to the cluster endpoint:

juju deploy mahout
juju add-relation mahout client

Network-Restricted Environments

Charms can be deployed in environments with limited network access. To deploy in this environment, configure a Juju model with appropriate proxy and/or mirror options. See Configuring Models for more information.

Verifying

Status

Apache Bigtop charms provide extended status reporting to indicate when they are ready:

juju status

This is particularly useful when combined with watch to track the on-going progress of the deployment:

watch -n 2 juju status

The message column will provide information about a given unit's state. This charm is ready for use once the status message indicates that it is ready.

Smoke Test

This charm provides a smoke-test action that can be used to verify the application is functioning as expected. Run the action as follows:

juju run-action mahout/0 smoke-test

Watch the progress of the smoke test actions with:

watch -n 2 juju show-action-status

Eventually, the action should settle to status: completed. If it reports status: failed, the application is not working as expected. Get more information about a specific smoke test with:

juju show-action-output <action-id>

Issues

Apache Bigtop tracks issues using JIRA (Apache account required). File an issue for this charm at:

https://issues.apache.org/jira/secure/CreateIssue!default.jspa

Ensure Bigtop is selected as the project. Typically, charm issues are filed in the deployment component with the latest stable release selected as the affected version. Any uncertain fields may be left blank.
