Subject [jira] [Commented] (SQOOP-2937) Sqoop mainframe module does not support sequential data sets, GDG, or data sets on tape
Date Mon, 30 May 2016 10:05:12 GMT

    [ https://issues.apache.org/jira/browse/SQOOP-2937?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15306468#comment-15306468

Attila Szabo commented on SQOOP-2937:

Hi all,

[~z17] many thanks for your highlights. I think generally you're absolutely right, that smaller
changes/patches are easier to review, and these should be reflected in subtasks. I have only
one concerns I'd like to raise here: in case of Sqoop1 connectors it's not always very easy
to separate things into smaller tasks/patches/commits, for example because "splitting" the
existing functionality would result in creating two new instead of the original solution,
but none of them would stand without the other one. So regarding to that I think we always
have to consider if it makes sense to have a series of different change, or one bigger squashed
patch/commit. But as I told: generally your approach should be the default.

[~chris.teoh@gmail.com] I'd like to ask the following things:
- First of all, assign the JIRA ticket to you, as you're the one who is working on it (and
have a working solution AFAIR).
- Updload the GDG related patch file to this ticket
- Please open a review ticket (on reviews.apache.org) with the patch file, and link the review
ticket to this JIRA ticket (you could do that by More->Link->Web link). You could add
me to that ticket as a reviewer (and optionally please add [~z17] too, I think it would be
a good opportunity for her to start with Sqoop1 development, anfter she's already quite experienced
with Sqoop2 )
- Please press "submit patch" button
- Please open a new ticket for the tape related changes, and do the very same process on that
one too (patch file, review ticket, etc.). Assign that ticket to you as well.
- Optionally (if it is feasible on your side): Please open another ticket as the parent ticket
of this, and convert the two previous ones to subtasks and link them together,

>             Project: Sqoop
>          Issue Type: Improvement
>          Components: connectors
>    Affects Versions: 1.4.6
>         Environment: mainframe
>            Reporter: Chris
>            Priority: Minor
>              Labels: patch
>             Fix For: 1.4.7
>   Original Estimate: 168h
>  Remaining Estimate: 168h
> The mainframe module (SQOOP-1272) currently supports partitioned data sets.
> I propose adding the following improvements:-
> - sequential data set support
> - GDG data set support
> - data sets stored on tape.
> I propose the following parameters to be added:-
> 1. --datasettype <p|s|g>  (p = partitioned data set, s = sequential, g = GDG)
> 2. --tape <true|false> (true = data set is on tape, false = data set is not on
> Let me know if this should be all in one issue or separate issues
