[jira] [Created] (TAJO-665) sort buffer size must be dealt as long type values.

Hyunsik Choi created TAJO-665:
---------------------------------

             Summary: sort buffer size must be dealt as long type values.
                 Key: TAJO-665
                 URL: https://issues.apache.org/jira/browse/TAJO-665
             Project: Tajo
          Issue Type: Improvement
            Reporter: Hyunsik Choi
            Assignee: Hyunsik Choi
             Fix For: 0.8-incubating, 1.0-incubating


sort buffer size (tajo.executor.external-sort.buffer-mb in TajoConf) is used to determine in-memory buffer for external merge sort. Currently, its type is integer. So, if users can set more than 2GB to sort buffer size, external merge operator will meet  negative sort buffer size. Finally, it will cause significant performance degradation.
