             Summary: Batch Scanner needs timeout
                 Key: ACCUMULO-705
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-705
             Project: Accumulo
          Issue Type: New Feature
          Components: client
            Reporter: Keith Turner
            Assignee: Billie Rinaldi
             Fix For: 1.5.0


The batch scanner needs a user configurable time out.  When the batch scanner is used to query
lots of tablet in parallel, if one tablet or tablet server is unavailable for some reason
it will cause the scan to hang indefinitely.  Users need more control over this behavior.

It seems like the batch scanner could behave in one of the following ways : 
  * Read as much data as possible, then throw an exception when a tablet or tablet server
has timed out
  * Throw an exception as soon as a tablet or tablet server times out, even if data could
still be read from other tablets successfully.
