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

             Summary: Sleep() function does not work.
                 Key: TAJO-1629
                 URL: https://issues.apache.org/jira/browse/TAJO-1629
             Project: Tajo
          Issue Type: Bug
          Components: function/udf
            Reporter: Jihoon Son
            Priority: Minor
             Fix For: 0.10.2


Sleep() function only works well in unit tests.
It seems that the following codes of Sleep() function make Tajo's task sleep.
{code}
...
public Datum eval(Tuple params) {
    try {
      Thread.sleep(params.getInt4(0) * 1000);
    } catch (InterruptedException e) {
      e.printStackTrace();
    }
...
{code}
