https://github.com/apache/hive/blob/ac6b2a3fb195916e22b2e5f465add2ffbcdc7430/ql/src/java/org/apache/hadoop/hive/ql/exec/OperatorFactory.java#L158

{code}
    } catch (Exception e) {
      e.printStackTrace();
      throw new HiveException(...
{code}

Do not print the stack trace.  The error is being wrapped in a HiveException.  Allow the code catching this exception to print the error to a logger instead of dumping it here to STDERR.  There are several instances of this in the class.
