> Implement Output Committer for commiting final output files
> -----------------------------------------------------------
>
> Key: TAJO-591
> URL: https://issues.apache.org/jira/browse/TAJO-591
> Project: Tajo
> Issue Type: Improvement
> Reporter: Hyunsik Choi
>
> In Tajo, when some task is failed, QueryMaster retries the task on another
> node. But, if the task belongs to the final step that generates output files
> in HDFS, this error occurs because the final output file already exists. In
> order to solve this problem, we have to implement some kind of output
> committer which would be similar to that of MR.
