5. Uninstalling HDP on All Nodes

On each cluster node, uninstall the HDP for Windows using one of the following methods:

  • Command line: Open the command prompt as an administrator and run the following command on each node in the cluster:

    msiexec /lv hdp_uninstall.log /qb  /x c:\MSI_INSTALLER\hdp-2.1.1.0.winpkg.msi HDP_DIR=C:\hdp DESTROY_DATA=no
    [Note]Note

    Use the MSI installer file that goes with the version of HDP you are uninstalling. For example, to uninstall HDP 1.3 use the hdp-1.3.0.0.winpkg.msi file. If you do not have the installer uninstall from the Program and Features > Uninstall Program window.

  • Control Panel: Open Programs and Features, and then right-click on Horton Works Data Platform for Windows and select Uninstall.

    This uninstall option keeps existing data in place, maintaining the data directories for HDFS and MapReduce.
