Brandon Li commented on HDFS-3763:
----------------------------------
Uploaded a patch for this issue. Basically, the patch provides a new method in
NN. This new method is used for error injection tests only, which closes the
edits stream(thus the file is released by NN) and replace it with a mocked
stream. The mocked stream can inject edits log access errors.

> One step of the test is to change the edit directory permission to "000" and
> then do rolledit. On linux rolledit operation will fail and the edit
> directory will be considered as failed by NN.
> However, changing the directory permission to 000 on Windows doesn't affect
> some accessibility of its sub-directories and files. Therefore, the edit
> files in the edit directory is still accessible and thus is not considered as
> "failed" by NN, which eventually causes test failure.
