[ https://issues.apache.org/jira/browse/HBASE-1158?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jim Kellerman updated HBASE-1158:
---------------------------------
Issue Type: Improvement (was: Bug)
> 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.
