> 1. everything broke. As I warned, Configuration is sensitive piece of code.
I am not sure the breakages are related. The error message is:
```
Unable to parse configuration fs.permissions.umask-mode with value
dfs.umaskmode as octal or symbolic umask.
```
and this change does not have any effect on parsing.
Do the tests work at HEAD? How can I trigger them?
> 2. can you not rebase and force push unless you absolutely have to, as it
complicates reviewing. thanks.
Sure. I will merge instead if that's more convenient.
