[jira] [Updated] (NIFI-6189) Offloading a shut down node will never
end until a full reset
[ https://issues.apache.org/jira/browse/NIFI-6189?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
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 :
# offloading timeout: have a property under the nifi.properties file to indicate how long to wait for a node to finish offloading before 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
