maghamravikiran commented on PHOENIX-2154:
------------------------------------------
>From the comments above, I see the below tasks
a) Provide options to end user to switch between bulk load or direct api
b) If direct api approach is chosen,
i) change the submission of job from an wait until completion to submit
the job and return immediately.
ii) Have a new Reducer that does the task of updating the status of the
index table .
I will work on this today .
Please feel free to add any task if I am missing .
> Failure of one mapper should not affect other mappers in MR index build

> Project: Phoenix
> Issue Type: Bug
> Reporter: James Taylor
> Attachments: IndexTool.java
>
>
> Once a mapper in the MR index job succeeds, it should not need to be re-done
> in the event of the failure of one of the other mappers. The initial
> population of an index is based on a snapshot in time, so new rows getting
> *after* the index build has started and/or failed do not impact it.
> Also, there's a 1:1 correspondence between index rows and table rows, so
> there's really no need to dedup. However, the index rows will have a
> different row key than the data table, so I'm not sure how the HFiles are
> split. Will they potentially overlap and is this an issue?
