> The full GC time of regionserver with big heap(> 30G ) usually can not be
> controlled in 30s. At the same time, the servers with 64G memory are normal.
> So we try to deploy multi rs instances(2-3 ) in a single node and the heap of
> each rs is about 20G ~ 24G.
> Most of the things works fine, except the hbase web ui. The master get the RS
> info port from conf, which is suitable for this situation of multi rs
> instances in a node. So we add info port to ServerName.
> a. at the startup, rs report it's info port to Hmaster.
> b, For root region, rs write the servername with info port ro the zookeeper
> root-region-server node.
> c, For meta regions, rs write the servername with info port to root region
> d. For user regions, rs write the servername with info port to meta regions
> So hmaster and client can get info port from the servername.
> To test this feature, I change the rs num from 1 to 3 in standalone mode, so
> we can test it in standalone mode,
> I think Hoya(hbase on yarn) will encounter the same problem. Anyone knows
> how Hoya handle this problem?
> PS: There are different formats for servername in zk node and meta table, i
> think we need to unify it and refactor the code.
