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
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
