Example 1 with AppendResponseProto

use of org.apache.hadoop.hdfs.protocol.proto.ClientNamenodeProtocolProtos.AppendResponseProto in project hadoop by apache.

the class ClientNamenodeProtocolTranslatorPB method append.

@Override
public LastBlockWithStatus append(String src, String clientName, EnumSetWritable<CreateFlag> flag) throws IOException {
    AppendRequestProto req = AppendRequestProto.newBuilder().setSrc(src).setClientName(clientName).setFlag(PBHelperClient.convertCreateFlag(flag)).build();
    try {
        AppendResponseProto res = rpcProxy.append(null, req);
        LocatedBlock lastBlock = res.hasBlock() ? PBHelperClient.convertLocatedBlockProto(res.getBlock()) : null;
        HdfsFileStatus stat = (res.hasStat()) ? PBHelperClient.convert(res.getStat()) : null;
        return new LastBlockWithStatus(lastBlock, stat);
    } catch (ServiceException e) {
        throw ProtobufHelper.getRemoteException(e);
    }
