Description

After upgrade from 1.16.0 to 1.17.0 i'm getting for each PutHDFS processor on nifi starup:

PutHDFS[id=1193119d-1eed-194e-bd1f-770a9d73ace1] Failed to determine ClassLoader Isolation Key for PutHDFS[id=1193119d-1eed-194e-bd1f-770a9d73ace1]. This could result in unexpected behavior by this processor.
