Hello,
I get the below error message in my NiFi logs when I tried to write a file to HDFS, but when i try to write a file with in the hadoop cluster it works fine, but from NiFi it fails with the below message.
My Nifi service is started by root and, when I have a local NiFi instance i am able to write the file to HDFS, where as from the NiFi cluster am unable to do so, any help would be highly appreciated, I am trying another solution, if that works then I will post it over here.
