Description
Apache Zeppelin is a web-based notebook that enables interactive data
analytics. You can make beautiful data-driven, interactive, and collaborative
documents with SQL, Scala and more.
Overview
Apache Zeppelin is a web-based notebook that enables interactive data analytics.
It allows for beautiful data-driven, interactive, and collaborative documents
with SQL, Scala and more.
As a Multi-purpose Notebook, Apache Zeppelin is the place for interactive:
- Data Ingestion
- Data Discovery
- Data Analytics
- Data Visualization & Collaboration
This charm deploys the Zeppelin component of the Apache Bigtop platform.
Deploying
A working Juju installation is assumed to be present. If Juju is not yet set
up, please follow the getting-started instructions prior to deploying this
charm.
This charm is intended to be deployed via one of the apache bigtop bundles.
For example:
juju deploy hadoop-processing
Note: The above assumes Juju 2.0 or greater. If using an earlier version of Juju, use juju-quickstart with the following syntax:
juju quickstart hadoop-processing.
This will deploy an Apache Bigtop Hadoop cluster. More information about this
deployment can be found in the bundle readme.
Now add Zeppelin and relate it to the cluster via the hadoop-plugin:
juju deploy zeppelin
juju add-relation zeppelin plugin
To access the web console, find the PUBLIC-ADDRESS of the
zeppelin application and expose it:
juju status zeppelin
juju expose zeppelin
The web interface will be available at the following URL:
http://ZEPPELIN_PUBLIC_IP:9080
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 zeppelin/0 smoke-test
Note: The above assumes Juju 2.0 or greater. If using an earlier version of Juju, the syntax is
juju action do zeppelin/0 smoke-test.
Watch the progress of the smoke test actions with:
watch -n 2 juju show-action-status
Note: The above assumes Juju 2.0 or greater. If using an earlier version of Juju, the syntax is
juju 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>
Note: The above assumes Juju 2.0 or greater. If using an earlier version of Juju, the syntax is
juju action fetch <action-id>.
