> DataXceiver#writeBlock
> {code:java}
> blockReceiver.receiveBlock(mirrorOut, mirrorIn, replyOut,
> mirrorAddr, null, targets, false);
> {code}
> As above code, DataXceiver#writeBlock doesn't throttler.
> I think it is necessary to throttle for writing block, while add throttler
> in stage of PIPELINE_SETUP_APPEND_RECOVERY or
> PIPELINE_SETUP_STREAMING_RECOVERY.
> Default throttler value is still null.
