Hello,
we faced the following problem after running this sequence:
Our cluster was running well for 24h on a single machine then one node was detected as
dead (without any obvious reason). Anyway, the node was shutdown as it discovered it was
ejected from the cluster view. Then, the coordinator get this error :
