[jira] [Created] (HBASE-7861) Use the ServerName in the Connection#getClient and Connection#getAdmin code

nkeywal created HBASE-7861:
------------------------------

             Summary: Use the ServerName in the Connection#getClient and Connection#getAdmin code
                 Key: HBASE-7861
                 URL: https://issues.apache.org/jira/browse/HBASE-7861
             Project: HBase
          Issue Type: Improvement
          Components: Client
    Affects Versions: 0.96.0
            Reporter: nkeywal
            Assignee: nkeywal
            Priority: Minor
             Fix For: 0.96.0


This is again a subpart of HBASE-7590. The patch already in HBASE-7590 contains a bad fix for this (confusion with seq number). This JIRA tries to fix it correctly.

The client code mostly uses hostname:port to get the connection to the region server. As a side effect if a server dies and comeback, the client won't notice. This is in theory, because the regions it's looking for are likely to be somewhere else.

In any case, if we add some dead server management in the client (HBASE-7590), we need to manage do the distinction between the server, to be sure that we're not declaring dead a server that has restarted.
