keith-turner opened a new pull request #1100: Avoid locking in tserver when reading online tablets
URL: https://github.com/apache/accumulo/pull/1100
 
 
   Profiling Accumulo during running a performance test showed lots of lock
   contention for the map of online tablets.  Most operations need to read
   this map.  This change creates a read only snapshot of the online
   tablets that is used to avoid lock contention.
