stack commented on HBASE-17194:
-------------------------------
There seems to be no relation between the current getOnlineServersList and the
new one below....
1096 public List<ServerName> getOnlineServersList(List<ServerName> keys,
1097 BiFunction<ServerName, ServerLoad, Boolean> predicater) {
Should the new one call the old one internally at least? Or iterate
this.onlineServers?
Does this happen alot?
Otherwise the patch looks good to me.
> Assign the new region to the idle server after splitting

> The new regions are assigned to the random servers after splitting, but there
> always are some idle servers which don’t be assigned any regions on the new
> cluster. It is a bad start of load balance, hence we should give priority to
> the idle servers for assignment.
