7. Set File Ownership

Warning

All files in the

D s item
iteminstall directory
and sub-directories must be owned by the same user that is used to run the

. Mismatches in ownership and execution permissions can cause services to fail to start.

Steps:

Before you upgrade, please complete the following:

  1. Login to the 
    D s node

  2. Execute the following command. The user that is being granted ownership of the install directory is trifacta, which is the default user that runs the platform. If you are using a different user to run your 

    D s item
    itemdeployment
    , please substitute that name.

    Code Block
    chown -R trifacta:trifacta /opt/trifacta
