[GitHub] [accumulo] milleruntime commented on issue #1606: Ability to disable scan file limit in FileManager

   Saw an issue where short scans were locking at this file limit gate so the client was killed.  The dead scans were stuck even after a client was killed and then new scans were waiting a long time at the semaphore for this file limit.  This situation could worsen as a user not seeing scans available, will retry creating more scans that get held up at this gate.   This is a situation where we want to prioritize scan availability over everything else, which is one of the trade offs @keith-turner mentions in https://issues.apache.org/jira/browse/ACCUMULO-416
