Failure to launch NiFi

Question

I have added some jar files to nifi lib folder to allow me to connect hive but unfortunately the nifi app not running in web , then I removed all the new jar files but the issue not fixed and I keep getting the following error (NIFI version 1.15.0)

ERROR [main] org.apache.nifi.NiFi Failure to launch NiFi due to java.lang.NoClassDefFoundError: org/apache/nifi/processor/DataUnit

What version of Java are you using? NiFi requires Java 8 or Java 11 (https://nifi.apache.org/docs/nifi-docs/) — tonykoval, Dec 28 '21 at 13:25
the obvious solution - reinstall nifi maybe you have removed some necessary jar files. — daggett, Dec 28 '21 at 20:39
To avoid potential issues, you can put custom jars into a separate folder and reference it in `nifi.properties` via `nifi.nar.library.directory.=`. See https://nifi.apache.org/docs/nifi-docs/html/administration-guide.html#installing-custom-processors — Fan Li, Jan 02 '22 at 03:33

I did find this answer that seems to point to the need to have declared the file in the pom. Apache Nifi failure due to java.lang.NoClassDefFoundError in a local maven dependency jar.
