Hi all, We're testing the new load-balance connection feature of NIFI 1.8.
After some cluster-wide restarts, some connections with load-balancing enabled seem to stuck.
The connection is always shown as actively balancing, however, the size of the queue show very little changes, also the queue contents cannot be viewed.
NIFI always returns that the queue has 0 flow files when trying to view queue content, despite showing a non-zero number in the UI and in REST.
When this happen, if we disable the load-balancing, we will be able to view the queue content immediately, but the problem return if we enable the load balancing feature again.
In addition, we sometime see negative queue size exception in the log when this happen, but not always.
Regards, Kien
