When input data is provided (into the Hadoop file system [HDFS]), it is first partitioned, and then distributed to map workers (via the job tracker).

在提供输入数据时(进入Hadoop文件系统[hdfs])，首先分段，然后分配给map工作线程(通过作业跟踪器)。

If the job completes, but the output file does not contain the transliterated output, check to see if the input file was saved as something other than UTF encoding, for example UCS.

如果作业完成，但输出文件没有包含经过音译的输出，请检查输入文件是否保存为utf编码之外的其他格式，比如ucs。

However, an output file tape may not be used by more than one job nor may it be used as an immediate input file.

然而，一个输出文件带不能被多个作业使用也不能作为立即输入文件。
