> Case Description:
> 1.Split hlog thread creat writer for the file region A/recoverd.edits/123456 
> and is appending log entry
> 2.Regionserver is opening region A now, and in the process 
> replayRecoveredEditsIfAny() ,it will delete the file region 
> A/recoverd.edits/123456 
> 3.Split hlog thread catches the io exception, and stop parse this log file 
> and if skipError = true , add it to the corrupt logsHowever, data in 
> other regions in this log file will loss 
> 4.Or if skipError = false, it will check filesystem.Of course, the file 
> system is ok , and it only prints a error log, continue assigning regions. 
> Therefore, data in other log files will also loss!!
> The case may happen in the following:
> 1.Move region from server A to server B
> 2.kill server A and Server B
> 3.restart server A and Server B
> We could prevent this exception throuth forbiding deleting  recover.edits 
> file 
> which is appending by split hlog thread
