Subject [jira] [Updated] (ACCUMULO-607) BatchScanner sometimes logs error when closed
Date Fri, 25 May 2012 16:56:22 GMT

     [ https://issues.apache.org/jira/browse/ACCUMULO-607?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Keith Turner updated ACCUMULO-607:
----------------------------------

    Description: 
The batch scanner has a threadpool.  When the batch scanner is closed it calls shutdownNow()
on this threadpool, which interrupts all of the threads.  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 no 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 where the background code calls UtilWaitThread.sleep().  There may be other places.
