I am using Apache NIFI 1.28 version and i have successfully configured the core-site.xml and hdfs-site.xml correctly. but when i run the processor it is giving the following error:

• 13:00:11 PKT ERROR PutHDFS[id=d2b7ad77-0192-1000-e937-9d1797c4e0fd] Failed to properly initialize Processor. If still scheduled to run, NiFi will attempt to initialize and run the Processor again after the 'Administrative Yield Duration' has elapsed. Failure is due to java.lang.NoClassDefFoundError: org/apache/commons/collections/map/UnmodifiableMap: java.lang.NoClassDefFoundError: org/apache/commons/collections/map/UnmodifiableMap - Caused by: java.lang.ClassNotFoundException: org.apache.commons.collections.map.UnmodifiableMap

I have included all possible combination of different jar files but all in vain, i am also attaching the lib folder as well
