> For namenode HA mode, standby namenode load editlog form journalnodes  via 
> QuorumJournalManger.selectInputStreams().  And RedundantEditLogInputStream is 
> used for combine multiple remote journalnode inputstreams.
> The problems is that when read editlog with 
> RedundantEditLogInputStream.nextOp() if the first stream execute skipUntil() 
> throw IOException ( network errors, or hardware problems etc..) ,  it will be 
> State.OK rather than State.STREAM_FAILED. 
> And the proper state will be like blew and fault tolerant:
> State.SKIP_UNTIL -> State.STREAM_FAILED ->(try next stream)  State.SKIP_UNTIL 
> -> State.OK
