Robbie Strickland commented on LOG4J2-240:
------------------------------------------
In my case, the failure occurred because I was attempting to use the file
channel on those nodes, but Hadoop (which is required for the file channel to
work) was not present. This caused the startup to fail and resulted in the
log4j error. So Flume was running but in a bad state, which seems to be the
root cause of the issue.
