Subject [jira] [Created] (ACCUMULO-757) Location for tablet assigned to dead server not removed when table offline

             Summary: Location for tablet assigned to dead server not removed when table offline
                 Key: ACCUMULO-757
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-757
             Project: Accumulo
          Issue Type: Bug
    Affects Versions: 1.3.5, 1.4.0
            Reporter: Keith Turner
             Fix For: 1.5.0


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.
