There may be other cases lurking where this kind of issue -- two servers are updating a particular row with off-clocks -- may bite us. Could a regionserver that has a clock a long ways behind the running master's clock enter a split record that went in behind the current inforegion cell's version? If so, the master wouldn't see the split. > One fix would be a new feature where cells had a version that autoincremented. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
