    // Overwrite
    boolean overwrite = createFlag.contains(CreateFlag.OVERWRITE);

    CreateOpts.BufferSize bufOpt = CreateOpts.getOpt(CreateOpts.BufferSize.class, opts);
    bufferSize = (bufOpt != null) ? bufOpt.getValue() : bufferSize;
    // replication
    short replication = fs.getDefaultReplication(f);
    CreateOpts.ReplicationFactor repOpt = CreateOpts.getOpt(CreateOpts.ReplicationFactor.class, opts);
    replication = (repOpt != null) ? repOpt.getValue() : replication;
    // blockSize
    long blockSize = fs.getDefaultBlockSize(f);
    CreateOpts.BlockSize blockOpt = CreateOpts.getOpt(CreateOpts.BlockSize.class, opts);
    blockSize = (blockOpt != null) ? blockOpt.getValue() : blockSize;
    // Progressable
    Progressable progress = null;
    CreateOpts.Progress progressOpt = CreateOpts.getOpt(CreateOpts.Progress.class, opts);
    progress = (progressOpt != null) ? progressOpt.getValue() : progress;
    return fs.create(f, permission, overwrite, bufferSize, replication, blockSize, progress);
}
