Check the NiFi Toolkit Symlink

In some upgrade scenarios the NiFi Toolkit may not be updated. After the installation you should check the NiFi Toolkit symlink and update it if necessary.

1. Navigate to the nodes where the NiFi, NiFi Registry, and NiFi Toolkit Certificate Authority services installed.
2. Check that the NiFi Toolkit symlink is pointing to the latest HDF version. On each node where the NiFi Toolkit is installed, run the following command:

   ls -al /usr/hdf/current

3. If the NiFi Toolkit symlink is pointing to an older version, update it by entering:

   hdf-select set nifi-toolkit [**new-version**]

   For example:

   hdf-select set nifi-toolkit 3.5.2.0-99
