giraph #5

Description

The Apache Giraph project's goal is to provide an environment that addresses
the challenges of Managing Big Graphs.

This charm provides version 1.1.0 of the Giraph application from Apache
Bigtop.


Overview

Apache Giraph is an iterative graph processing system built for high scalability. For example, it is currently used at Facebook to analyze the social graph formed by users and their connections. Giraph originated as the open-source counterpart to Pregel, the graph processing architecture developed at Google and described in a 2010 paper. Both systems are inspired by the Bulk Synchronous Parallel model of distributed computation introduced by Leslie Valiant. Giraph adds several features beyond the basic Pregel model, including master computation, sharded aggregators, edge-oriented input, out-of-core computation, and more. With a steady development cycle and a growing community of users worldwide, Giraph is a natural choice for unleashing the potential of structured datasets at a massive scale.

This charm deploys version 1.1.0 of the Giraph 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 Giraph and relate it to the cluster endpoint:

juju deploy giraph
juju add-relation giraph 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 giraph/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>

Configuration

bigtop_version
(string) Apache Bigtop release version. The default, '1.2.0' will use the current GA release, Bigtop 1.2.0, for all hiera data, puppet recipes, and installable packages. Set this to 'master' to use the latest upstream bits.
1.2.0
cuda-version
(string) The cuda-repo package version to install.
8.0.61-1
install-cuda
(boolean) Install the CUDA binaries if capable hardware is present. This option is False by default, as not all applications support GPU acceleration.
