FSDownload.getFileStatus介绍

[英]Obtains the file status, first by checking the stat cache if it is available, and then by getting it explicitly from the filesystem. If we got the file status from the filesystem, it is added to the stat cache. The stat cache is expected to be managed by callers who provided it to FSDownload.
[中]获取文件状态，首先检查stat缓存是否可用，然后从文件系统显式获取。如果我们从文件系统获得文件状态，它将被添加到stat缓存中。stat缓存应该由提供给FSDownload的调用方管理。
