keith-turner opened a new issue #854: Tablet server should compact all tablets referencing older logs
URL: https://github.com/apache/accumulo/issues/854
 
 
   The tablet server minor compacts any tablet that reference more than 5 write ahead logs.  With per tablet server write ahead log tracking all write ahead logs referenced by any tablet are assigned to all tablets at recovery time.  This means that individual tablets may end up trying to recover from man write ahead logs.
   
   When a tablet server has more than 5 write ahead logs then it should probably minor compact/flush any tablet referencing the WALs created before the 5th one.  These tablets themselves may have less than 5 write ahead logs.
