I can't think of something in the new Monitor code that can already do this. |

The is beginning of an attempt to address #6306, however making it a bit more general. Trying to detect not just recovery, but any cause of not being able to scan the root or metadata table. The code is not worth looking ATM, posting this more for discussion.
Would like to get to get a point where I can detect a problem w/ root or metadata table scans and display a header message on every monitor page. @DomGarguilo or @dlmarion do you know of anything in the monitor that can do this currently? Would like to display a message like
Can not scan all 15 accumulo.metadata tablets because 5 are unhosted and 2 are recovering. This may impact data displayedat the top of every page when there is problem.
