ZDP ansible installer inventory feedback

ZDP ansible installer inventory feedback

  • Variables added primarily for internal purpose should not be exposed to customers(e.g cleanup_zdp_database).

    • can be managed through an internalONLY inventory.

    • most of customer install/upgrade will not be using this

  • Instead of one example inventory, publish inventory references for different deployments

    • singlenode inventory for cdh

    • singlenode inventory for hdp

    • singlenode inventory for emr

    • singlenode inventory for hdinsight

    • multinodeHA inventory for cdh

    • multinodeHA inventory for hdp

    • multinodeHA inventory for emr

    • multinodeHA inventory for hdinsight

    • multinodeHAtransientEMR inventory

    • multinodeHAtransientHDInsight inventory

  • If ansible installer have intelligence to identify hadoop distro type then the number of reference inventory to be published and the number of inventory configuration can be significantly reduced by handling the logic through ansible playbook tasks
