Nimrod Avni updated NIFI-6189:
------------------------------
Description:
If a situation occurs where one of your nodes is unresponsive, and you attempt
to offload it, it will be stuck in offloading status for ever until a full (not
rolling) restart will occur
This is a serious problem considering if your cluster does not have all it's
nodes connected you can't operate/create anything in it, for you to do it will
require you to shut down your entire cluster and start it over again
my suggestion for a solution is one of the following:
# offloading timeout: have a property under the nifi.properties file to
indicate how long to wait for a node to finish offloading before forcing it to
stop and considering it disconnected
# force offload to stop: have an option to force stop the offloading of a
node. making it disconnected
I found a hortonworks tread about this same issue
