apache hadoop client #6

Supports: trusty


Hadoop is a software platform that lets one easily write and run applications that process vast amounts of data. This charm manages a dedicated client node as a place to run mapreduce jobs.


The Apache Hadoop software library is a framework that allows for the distributed processing of large data sets across clusters of computers using a simple programming model.

This charm deploys a client node running Apache Hadoop 2.4.1 from which workloads can be manually run.


This charm is intended to be deployed as a part of the core bundle:

juju quickstart apache-core-batch-processing

This will deploy the Apache Hadoop platform with a single client unit. From there, you can manually load and run map-reduce jobs:

juju scp my-job.jar client/0:
juju ssh client/0
hadoop jar my-job.jar
