----------------------------------

             Summary: Do Not Print StackTraces to STDERR in 
AbstractJoinTaskDispatcher
                 Key: HIVE-20162
                 URL: https://issues.apache.org/jira/browse/HIVE-20162
             Project: Hive
          Issue Type: Improvement
          Components: Query Planning
    Affects Versions: 3.0.0, 4.0.0
            Reporter: BELUGA BEHR


https://github.com/apache/hive/blob/6d890faf22fd1ede3658a5eed097476eab3c67e9/ql/src/java/org/apache/hadoop/hive/ql/optimizer/physical/AbstractJoinTaskDispatcher.java

{code}
    } catch (Exception e) {
      e.printStackTrace();
      throw new SemanticException("Generate Map Join Task Error: " + 
e.getMessage());
    }
{code}

Remove the call to {{printStackTrace}} and just throw the error.  If the stack 
trace really is needed (doubtful), then pass it to the {{SemanticException}} 
constructor.
