Yeah, HServerInfo sounds like a better place for the startcode.

>                 URL: https://issues.apache.org/jira/browse/HBASE-1158
>             Project: Hadoop HBase
>          Issue Type: Improvement
>    Affects Versions: 0.20.0
>            Reporter: Jim Kellerman
>             Fix For: 0.20.0
> If we do not take the startcode into consideration when recovering from a server death,
then we cannot know if the data in ROOT or META pertains to the the current instance or the
previous one.
> With ZK this should be easier if we modify HServerAddress to contain the startCode of
a HRegionServer instance. It would be immediately visible whether or not the region was on
the dead server or the new server.
