             Summary: BatchScanner sometimes logs error when closed
                 Key: ACCUMULO-607
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-607
             Project: Accumulo
          Issue Type: Bug
          Components: client
    Affects Versions: 1.4.0, 1.3.5
            Reporter: Keith Turner
            Assignee: Billie Rinaldi
             Fix For: 1.5.0


The batch scanner has a threadpool.  When the batch scanner is closed it calls 
shutdownNow() on this threadpool, which interrupts all of the thread.  If a 
user does not read all data from a batch scanner and calls close, thens its 
likely that the background threads are still busy and will be interrupted.  
This is a normal course of business, so there is not need to log an exception 
for these interrupted excpetions.  Some places in the code do log an error when 
these exceptions occur.  

One place is there the background code call UtilWaitThread.sleep().  There may 
be other places.
