[jira] [Created] (TAJO-1651) Too long fetcher default retries

Jinho Kim created TAJO-1651:
-------------------------------

             Summary: Too long fetcher default retries
                 Key: TAJO-1651
                 URL: https://issues.apache.org/jira/browse/TAJO-1651
             Project: Tajo
          Issue Type: Improvement
          Components: data shuffle
    Affects Versions: 0.10.0, 0.9.0, 0.10.1
            Reporter: Jinho Kim
            Priority: Minor


The fetcher is getting an intermediate file from PullServer. fetcher will retry, when fails.
Currently, maximum timeout is task-retry(3) * fetch-retry(20) * timeout(120 sec)
I suggest that SHUFFLE_FETCHER_READ_RETRY_MAX_NUM change to  2
{noformat}
SHUFFLE_FETCHER_READ_TIMEOUT("tajo.shuffle.fetcher.read.timeout-sec", 120)
SHUFFLE_FETCHER_READ_RETRY_MAX_NUM("tajo.shuffle.fetcher.read.retry.max-num", 20)
{noformat}
