Hi all,
I’m preparing to upgrade some NiFi clusters from 1.12 to 1.18 (after making a
pit stop at 1.16 for sensitive dynamic properties conversion).
After upgrading a test server, all HDFS processors show as invalid with an
error that the path ‘${ADDITIONAL_CLASSPATH}’ could not be found for the
additional classpath property.
It appears that the processors no longer support a variable or parameter for
this setting. I assume this is because of the improvements in how the
processors are loaded.
Due to the number of processors involved, it seems I will need to do a
search/replace through the flow.json.gz to update these. I’m hesitant to
hardcode the value in case future changes are needed.
My question is: Can I safely add the Azure libraries currently located in the
additional classpath to either an additional nifi libs dir specified in
nifi.properties or the autoload directory?
Would they be available to the HDFS processors and not cause any performance
problems? That would hopefully allow me to empty the additional classpath
property and still be able to make changes in one place later.
Kind regards,
Isha
