> I traced the code and found the following assertion failed :
> /* org.apache.cassandra.locator.AbstractReplicationStrategy.getHintedMapForEndpoints(Collection<InetAddress>) */
> assert map.size() == targets.size();
> The following reasons caused this issue:
> 1) targets is a list , not a map, as a result there may be some duplicated IP.
> 2) The following codes are not atomic :
> org.apache.cassandra.service.StorageService.handleStateNormal(InetAddress, String)
> tokenMetadata_.updateNormalToken(token, endPoint);
> calculatePendingRanges();
> That's to say the IP may be both in the naturalEndpoints and pendingRanges.
> eg :
> targets is IPa, IPb, IPc, IPa; (size = 4)
> then, the map will be IPa, IPb, IPc. (size = 3)
> as a result, assert failed.
