----------------------------------
Summary: Add info port to ServerName to support multi instances in
a node
Key: HBASE-9892
URL: https://issues.apache.org/jira/browse/HBASE-9892
Project: HBase
Issue Type: Improvement
Reporter: Liu Shaohui
Assignee: Liu Shaohui
Priority: Minor
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.
