Mai Hai Thanh updated TAJO-983:
-------------------------------
Attachment: TAJO-983.140902.patch
Thank Hyunsik! I fixed the bug and uploaded the new patch to both this Jira
page and the review board: https://reviews.apache.org/r/25242/
I also tried to refactor the code to avoid code copying. However, after
refactoring, many tests failed due to an exception throw by Netty and I could
not find a solution. In summary, except the copying of some code, other things
go well.
Beside, now I have a patch file, how can I open a pull request as often be seen
by other members ? (Looking at the pull requests made by others, I like Git's
interface more than that of the review board)

> Currently, worker always fetches all intermediate via Fetcher and than store
> them in local file system even though some intermediate data already are
> stored in local file system. It is inefficient and causes unnecessary I/O and
> extra storage occupation. We should improve it.
