示例1: NewChecksumReader

// NewChecksumReader creates a new ChecksumReader for the given block.
func NewChecksumReader(block *hdfs.LocatedBlockProto) *ChecksumReader {
	locs := block.GetLocs()
	datanodes := make([]string, len(locs))
	for i, loc := range locs {
		dn := loc.GetId()
		datanodes[i] = fmt.Sprintf("%s:%d", dn.GetIpAddr(), dn.GetXferPort())
	}

	return &ChecksumReader{
		block:     block,
		datanodes: newDatanodeFailover(datanodes),
	}

示例2: NewBlockReader

// NewBlockReader returns a new BlockReader, given the block information and
// security token from the namenode. It will connect (lazily) to one of the
// provided datanode locations based on which datanodes have seen failures.
func NewBlockReader(block *hdfs.LocatedBlockProto, offset int64, clientName string) *BlockReader {
	locs := block.GetLocs()
	datanodes := make([]string, len(locs))
	for i, loc := range locs {
		datanodes[i] = getDatanodeAddress(loc)
	}

	return &BlockReader{
		clientName: clientName,
		block:      block,
		datanodes:  newDatanodeFailover(datanodes),
		offset:     offset,
	}
}
