Lars Hofhansl commented on HBASE-9892: -------------------------------------- This is currently marked fixed, but I do not think it was commited to 0.96. I would like this in 0.94 as well. Should I reopen, or rather create a backporting issue for 0.94 and 0.96? > 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: Critical > Fix For: 0.98.0, 0.96.2, 0.99.0 > > Attachments: HBASE-9892-0.94-v1.diff, HBASE-9892-0.94-v2.diff, > HBASE-9892-0.94-v3.diff, HBASE-9892-0.94-v4.diff, HBASE-9892-0.94-v5.diff, > HBASE-9892-0.94-v6.diff, HBASE-9892-trunk-v1.diff, HBASE-9892-trunk-v1.patch, > HBASE-9892-trunk-v1.patch, HBASE-9892-trunk-v2.patch, > HBASE-9892-trunk-v3.diff, HBASE-9892-v5.txt > > > 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. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
