Hi,
Can you check nifi-app.log file instead of bootstrap?
You have a bulletin generated (red icon) and you should have more information
in the nifi-app.log file.
Thanks!

I am getting an error of 'Administratively Yielded for 1 sec due to processing
failure' and the files that are triggering the error in the processor are not
getting routed to the failure processor but seem to loop and stop up the first
processor. Any ideas on how to resolve?
I would expect the files that are loaded that cause the error would get routed,
but instead it appears as though it eventually just stops accepting new files
all together since the queue
No errors in nifi-bootstrap.log. It runs for a while then gradually slows down
and stops processing new files.
Tried increase the memory heap to 1,024 MB, but got an error when tried to
follow the
https://community.hortonworks.com/articles/7882/hdfnifi-best-practices-for-setting-up-a-high-perfo.html
recommended 8g settings.
