[jira] [Created] (DRILL-2916) Queries fail due to bug in assignment code

Steven Phillips created DRILL-2916:
--------------------------------------

             Summary: Queries fail due to bug in assignment code
                 Key: DRILL-2916
                 URL: https://issues.apache.org/jira/browse/DRILL-2916
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Steven Phillips


There are some instances where there will be no work units assigned to minor fragment. This causes the query to fail.

This is a regression due to the changes in the AssignmentCreator logic. It is susceptible to hit this bug when the number of files is much larger than the number of leaf fragments.
