首先，我用FileScanner找到清单8中的checksum方法创建的每个校验和文件。

First, I've used a FileScanner to find every checksum file created from the checksum method from Listing 8.

当某个客户端创建一个新的HDFS文件，会计算这个文件每个block的校验和，并作为一个单独的隐藏文件保存这些校验和在同一个HDFS namespace下。

When a client creates an HDFS file, it computes a checksum of each block of the file and stores these checksums in a separate hidden file in the same HDFS namespace.

创建简单的报告，列出每个类文件及其对应的校验和。

Create a simple report that lists each class file and its corresponding checksum.
