> {{DFSStripedOutputStream}} will continue writing with minimum number
> (dataBlockNum) of live datanodes. It won't replace the failed datanodes
> immediately for the current block group. Consider a case where all the parity
> data streamers are failed, now it is unnecessary to encode the data block
> cells and generate the parity data. This is a corner case where it can skip
> {{writeParityCells()}} step.
