    I have already deployed a 13 nodes HDP Cluster via Ambari
    Are there any guides that provide SOP for HDP users to upgrade their HDP cluster from to instead of upgrading from HDP 1.X to HDP 2.X ?

    Hi James,

    You don’t have to upgrade ambari, if you want you can follow this docuement and see if this applies to your situation:

    If you are using ambari, to upgrade the OS, please follow this:

    This seems like a big project, I would suggest you do this to your dev / POC cluster first, before moving to production. If any further assistance is needed, I would suggest you refer to Hontorworks consulting for professional assistance.

    Hi Kenny,
    Thanks for your kindly give me the hint. After reading the upgrade guide, I list my upgrade steps as following, could you or any expert in this forum can review my
    steps? Owing to this is my production cluster, I must do everything carefully

    Step 1.
    Stop the HDP cluster by using Ambari
    or manually stop cluster as the following Hortonworks official guide will be better?

    Step 2.
    Upgrade OS (CentOS 6.5 )

    Step 3.
    Upgrade HDP to by following Hortonworks’ official guide :

    Step 4.
    Start the HDP cluster by using Ambari
    or manually start cluster as the following Hortonworks official guide will be better?

    In above steps, it seems does not upgrade the ambari server and agent ? Am I right? If so, what’s the SOP for upgrading the Ambari server and agent?
    Should I upgrade ambari before upgrading HDP? (i.e. Before step 3?)

    Should I modify/update the repo files in each node’s /etc/yum.repos.d/ first? Where is the latest repo file for HDP

    One more thing, If I want to upgrade the JDK to JDK7 instead of continue to use the currently using version of JDK(jdk1.6.0_31) which come with HDP
    how should I do?

    Best Regards,
    James Chang
