> FSEditLog.open will be invoked when SecondaryNameNode doCheckPoint,
> If no dir is opened successfully, it only prints some WARN messages in log,
> and goes on running. 
> However, it causes the editStreams becomes empty and cannot by synced 
> in. And if editStreams were decreased to 0 when exceptions occured during
> logsync, NameNode would print FATAL log message and halt itself. Hence,
> we think it should also stopped itself at that time.
