> Our cluster have 40G fsimage, we write one copy of edit log to NFS.
> After NFS temporary failed, when doing checkpoint, NameNode try to recover it, and it
will save 40G fsimage to NFS, it takes some time (> 40G/128MB/s = 320 seconds) , and it
locked FSNamesystem, and this bring down our cluster.
