Subject [jira] [Created] (ACCUMULO-607) BatchScanner sometimes logs error when closed
Date Fri, 25 May 2012 16:54:22 GMT
Keith Turner created ACCUMULO-607:
-------------------------------------

             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.
