Joseph Gresock updated NIFI-3897:
---------------------------------
Description:
A particular queue is listed as having 80,000 flow files, but NiFi thinks there
are none to list. I am inclined to believe that the queue is indeed empty, and
that there is somehow a pointer to 80,000 flow files leftover on the queue.
Unfortunately, the logs have rolled over so I can't see what error or warning
messages may have happened at the time, and I can't reproduce it reliably.
Update: I happened to reboot my cluster, and suddenly the 80,000 flow files
went through the flow. This makes the problem considerably worse, since it
appears the flow files were "invisible" until the reboot.
