Jim Kellerman commented on HBASE-1158:
--------------------------------------
The start code needs to be associated with the address in some manner for
server death recovery (see HBASE-1156). Whether it is carried around with the
HServerAddress or not is really more a consideration for ZK than anything else.
Inside the master we currently pass around HServerInfo's which carry both the
start code and the load information (although one could make a case to separate
the load from HServerInfo as well, since the master manipulates load
information separately from the address and start code)
> Include start code as part of HServerAddress

> Project: Hadoop HBase
> Issue Type: Sub-task
> 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.
