Once we name the Hadoop cluster, we are presented with a screen to select the version of Hadoop we want to run.
At the time of writing, Ambari supports the following Hadoop versions:
- Hadoop 2.3
- Hadoop 2.4
- Hadoop 2.5
- Hadoop 2.6 (upto 2.6.3.0)
You can choose any version for the installation. I have selected the default option which is version 2.6.3.0, which can be seen in this screenshot:
Click Next at the bottom of the screen to continue to the next step.
