> When a table is offline and some of its tablets have locations that map to dead servers,
those locations are never removed.   Some features wait for a table to go offline by scanning
the metadata table until no tablet has a location.  These features will get stuck in this
case.
> I was trying to test a recent patch to ACCUMULO-456 before applying the patch.  To test
the patch I needed a offline tablet to have a walog and no location.   In an attempt to create
this situation I did the following :
>   * create table X
>   * write data to table X
>   * kill tablet server serving table X tablet
>   * offline table before tablet is reassigned 
> When the above steps happen, the tablets location is never removed by the master.
