> Currently NM is able to kick bad directories out when they fail, but not able to reuse
them if they are fixed. This is inconvenient in large production clusters. 
> In this jira I propose a patch that I am using in my organization. 
> It also adds a new metric of the number of failed directories so people have clearer
view from outside.
