> 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.
