Ambari 2.7.0 verifies your NiFi Toolkit versions, and requires that you have one that
matches the version of NiFi and NiFi Registry that you have installed. Before you begin the
upgrade process, verify that you have the necessary version of the NiFi Toolkit.
-
Identify the version of NiFi and NiFi Registry that you have installed.
run hdf-select status | nifi
run hdf-select status | nifi-registry
This returns the stack version of NiFi and NiFi Registry. For example, if you
have HDF 3.1.x installed, hdf-select returns something
similar to:
nifi - 3.1.1.0-35
nifi-registry - 3.1.1.0-35
-
Ensure that var/lib/ambari-agent/tmp contains a version of
the NiFi Toolkit that contains this stack version. For example, based on the
above returns, you should have a NiFi Toolkit directory named
nifi-toolkit-1.5.0.3.1.1.0-35.
-
If you do not have the required directory, copy an existing NiFi Toolkit
directory and rename it using version and build number appropriate for your
installation.
-
Ensure that the service user is the owner of the copied directory.
