HDP on Linux – Installation Forum

How to Install Newer Version of Java

    Hi,

    I need to update the version of java we are using in our HDP cluster due to company IA requirements and security concerns with java version 1.6_31.

    At a minimum, I need to update to version 1.6_45.

    Question #1: Will Ambari run under this version? (I’ve been unsuccessful with getting Java 1.7 to work).

    Question #2: What is the best way to change the version of java, my current operational cluster(HDP 1.3.0) is using?

    Thanks,

    Ray

    Hi Ray,

    I would advise that you do this on a test cluster first.
    I will test on mine but I can’t say if it’s supported or not.

    Thanks

    It looks like Ambari 1.2.5 and up is find with using Java 1.7. Also, the latest Ambar 1.4, officially supports it.

    Now, once we get Accumulo support, Hortonworks will take over the world!! :)
