[jira] [Created] (TRAFODION-3315) OSIM gives no error detail when Hive failures occur

David Wayne Birdsall created TRAFODION-3315:
-----------------------------------------------

             Summary: OSIM gives no error detail when Hive failures occur
                 Key: TRAFODION-3315
                 URL: https://issues.apache.org/jira/browse/TRAFODION-3315
             Project: Apache Trafodion
          Issue Type: Improvement
          Components: sql-cmp
            Reporter: David Wayne Birdsall
            Assignee: David Wayne Birdsall
             Fix For: 2.4


OSIM load under the covers uses Hive to load histogram data into the histogram metadata tables.

When there is a failure at the Hive level, OSIM reports only:

*** ERROR[6009] The Optimizer Simulator (OSIM): Error running hive SQL.

This is not at all helpful in diagnosing the problem.

We should change OSIM so that it also reports the error information returned from Hive.
