    Hi,
    I have already deployed a 13 nodes HDP 2.0.6.0 Cluster via Ambari 1.4.2.104-1.
    Are there any guides that provide SOP for HDP users to upgrade their HDP cluster from 2.0.6.0 to 2.0.9.0 instead of upgrading from HDP 1.X to HDP 2.X ?

    Best Regards,
    James Chang

    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: http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.0.9.0/bk_using_Ambari_book/content/ambari-chaplatambv.html.

    If you are using ambari, to upgrade the OS, please follow this: http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.0.9.0/bk_using_Ambari_book/content/ambari-chap8.html.

    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.

    Thanks,
    Kenny

    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 2.0.6.0 cluster by using Ambari
    or manually stop cluster as the following Hortonworks official guide will be better?

    http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.0.9.0/bk_reference/content/reference_chap3_2.html

    Step 2.
    Upgrade OS (CentOS 6.5 )

    Step 3.
    Upgrade HDP 2.0.6.0 to 2.0.9.0 by following Hortonworks’ official guide :

    http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.0.9.0/bk_releasenotes_hdp_2.0/content/ch_relnotes-hdp-2.0.9.0-whats-changed-stack.html

    Step 4.
    Start the HDP 2.0.9.0 cluster by using Ambari
    or manually start cluster as the following Hortonworks official guide will be better?

    http://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.0.9.0/bk_reference/content/reference_chap3_1.html

    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 2.0.9.0?

    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 2.0.6.0
    how should I do?

    Best Regards,
    James Chang
