stack commented on HBASE-6858:
------------------------------

bq ....write the same data same version again.

Same znode id, same seed (generated by different SecureRandom instances), 
around same time, and same data... seems highly unlikely?  The extra integer 
seems too much to me.
                
> Fix the incorrect BADVERSION checking in the recoverable zookeeper

> Thanks for Stack and Kaka's reporting that there is a bug in the recoverable 
> zookeeper when handling BADVERSION exception for setData(). It shall compare 
> the ID payload of the data in zk with its own identifier.
