running Hadoop & Big Data on Oracle Cloud Infrastructure

Create Hadoop Instance on Oracle Cloud : login to oracle.bitnami.com , select Hadoop image and launch it on Oracle Cloud Infrastructure OCI Classic , for this you would need to create a connection between Oracle IaaS and Bitnami

Open required ports : Once the instance has been created you should be able to see hadoop admin console and hdfs directory browser web interface, this would need you open the port through a tunnel using putty

Hadoop Cloud Web Console

http://public_ip/cluster/nodes

Using Putty Open tunnel for port 50070

So the web console to view HDFS will be available at http://localhost:50070/explorer.html

Checking in and viewing files in HDFS

Hadoop Create Directory and Check In file

We will create an HDFS directory, check in a file , view the hdfs file and view the same file in the Browser console
