A tablet is uniquely identified by : (table id, end row, and previous end
row). In the Accumulo internal code KeyExtent is used to hold this info.
Other internal code can extract KeyExtents from the the metadata table.
Are you interested in a pointer to this code? Its not public API, but I can
help you find the code if thats what you are looking for.
Inoder to avoid leaking sensitive on the monitor page, KeyExtent has a
method that returns hash((table id, end row, and previous end row). This
hash could serve as an ID. Or you could hash, encrypt, encode etc info
that yourself with a different function.
