> {code}
> String mId = "" + doc.get(MACHINE_ID_KEY);
> String iId = "" + doc.get(INSTANCE_ID_KEY);
> if (machineId.startsWith(RANDOM_PREFIX)) {
> // remove expired entries with random keys
> store.remove(Collection.CLUSTER_NODES, key);
> continue;
> }
> {code}
> The intent seems to be to cleanup entries in the cluster node table that start with RANDOM_PREFIX. However, {{machineId}} is checked instead of {{mId}}. When {{createInstance}} is called with a random id, the whole table might get wiped out.
