Description

Class org.apache.hadoop.hive.ql.exec.JoinOperator has the following code:

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

Do not print the stack trace to STDERR with a call to printStackTrace(). Please remove that line and let the code catching the HiveException worry about printing any messages through a logger.
