Upgrade the Hadoop version from 2.6.0.3 to 2.6.3

enter image description herewe have hadoop cluster with HDP version - 2.6.0.3

our target is to upgrade the version from 2.6.0.3 to 2.6.3 ( 2.6.3 is the last certified version )

this upgrade can be done by Ambari GUI and by clicking the relevant TAB's

but we want full upgrade automation by CLI or REST API

is it possible? , and if yes can we get info about this Rest API ?

Solution

  • You seem to be confused that Hortonworks HDP, Ambari, and Hadoop all maintain individual versions.

    HDP has maintained Hadoop 2.7.3 for quite some time.

    Ambari 2.6.x would be installed by your OS package manager, and you need to stop both the server and the agents in order to upgrade it. Therefore, there will be no REST calls being made. With that version of Ambari, you can upgrade the HDP stack definitions (maybe via REST), but you'll still need to trigger an upgrade and rolling restart action. And the latest HDP is actually 2.6.4, and I'm not sure I understand what a "certified version" is, but I imagine it's no different than "generally available, released" version.

    The entire upgrade process is outlined in the HDP Upgrade documentation
