------------------------------
Yeah, HServerInfo sounds like a better place for the startcode.
> Include start code as part of HServerAddress

> Key: HBASE-1158
> 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.
