How to disable JDK installation when using Cloudera Director

[#1]

Hi,

I am using Cloudera Director for deploying CDH in AWS. But it installed JDK 1.7 by default. Is there a switch to disable that in Cloudera Director configuration files?

There is, actually! In the cloudera-manager section, you can set javaInstallationStrategy to NONE:

...
cloudera-manager {

    javaInstallationStrategy: NONE
    ...
}

Keep in mind that you'll need to install Java yourself, either by including it with your AMI of choice or using a bootstrap script. If you use a bootstrap script, you may be interested in this instance bootstrap script sample, which will install Java 8 on your Cloudera Manager/cluster.

Thank you Mike! I have a custom AMI with JDK pre-installed.
