Question

 # pick up the file which needs to be processed
    current_file = file_names[0]
    print "Processing current file: " + current_file

    key = bucket.get_key(current_file)
    print "Processing key: " + str(key)
    key.get_contents_to_filename(working_dir + "test_stats_temp.dat")
    print "Current directory: ",outputdir
    print "File to process:",current_file

处理测试输出：ds=2013-08-27

处理当前文件：output/test_count_day/ds=2013-08-27/task_201308270934_0003_r_000000

处理键：键：hadoop.test.com,output/test_count_day/ds=2013-08-27/task_201308270934_0003_r_000000

当我从 S3 输出将数据提取到 DB 时，出现此错误。我在这里很困惑。如何处理这个问题？

Answer 1

错误：

IOError: [Errno 2] No such file or directory: '/home/sbr/aaa/test_stats_temp.dat'

表示working_dir设置的路径不存在。创建目录将修复它。
