Corona Single Node Setup

Single Node Corona Cluster

This wiki provides instructions for starting a pseudo-distributed Corona Cluster on a single machine.

Building

ant -Dversion=0.20 jar bin-package

Starting up the cluster

First, set up the required environment and useful aliases.

source singleNodeSwitch.sh corona

Then start the cluster

If this is the first time, format the namespace in /tmp with hadoop namenode -format

Start HDFS:

start-dfs

Start Corona:

start-corona

There are corresponding commands to stop the clusters - stop-dfs, and stop-corona

At this point you will be able to look at the Corona Cluster Manager UI at http://localhost:50032/cm.jsp
