HConnectionManager cache server name enhancement
------------------------------------------------
Key: HBASE-5310
URL: https://issues.apache.org/jira/browse/HBASE-5310
Project: HBase
Issue Type: Improvement
Components: client
Affects Versions: 0.94.0
Reporter: Jimmy Xiang
Assignee: Jimmy Xiang
Priority: Minor
Fix For: 0.94.0
Attachments: hbase-5310.txt
HConnectionManager uses deprecated HServerAddress to create server cache key
which needs to resolve the address every time.
It should be better to use HRegionLocation.getHostnamePort() instead.
In our cluster we have some DNS issue, resolving an address fails sometime
which kills the application since it is a runtime
exception IllegalArgumentException thrown at HServerAddress.getResolvedAddress.
This change will fix this issue as well.
