[CONTROLLER-1473] Node exists in entity-owner data even after killing the instance

Duplicate — Thu, 19 Oct 2017 22:33:46 +0000

In ovsdb southbound 3 nodes clustering csit,

ovsdb-csit-3node-clustering-only-beryllium

when a node goes down and if i check the entity owner among the other two nodes
the member 1/2/3 which is killed should not exist but its there in the candidates list.

Added more delay of 20s to get the entity owner after killing one node. But still the down node exist in operational ds for entity candidates list.

Here goes the log for the observed behaviour:
