The test covers scenarios where:

The directory contains a mix of complete fsimage files and one that is currently being copied.
The FsImageWatcher should correctly ignore the 'COPYING' file and return the latest complete fsimage file.

Thx alot, @spearkkk !

I believe a COPYING file would be created by a 3rd party accessing the fsimage directory?

spearkkk commented 2 weeks ago

@marcelmay right, it is created by file copying operation by other accessing. I just thought that test case would help me understand REGEX of filter.
