Subject [jira] [Commented] (HADOOP-12547) Remove hadoop-pipes
Date Wed, 04 Nov 2015 16:07:28 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-12547?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14989803#comment-14989803

Kihwal Lee commented on HADOOP-12547:

bq. My guess is no, given most of that team has left/was shipped over to Microsoft.
That was certainly the case at one point in the past (2.5 CEOs ago), but you all know nothing
stays the same in this business for long.

I think we have internal users who depend on pipes. We will find out whether they can move
on to streaming. If they can't because of any fundamental shortcomings of streaming, we will
need to address those.

bq. I don't think we can remove in branch-2, but let's do this for trunk.
I think the source of confusion is the tile, "Remove hadoop-pipes" and setting the target
to 2.8. I will change the title to "deprecate".

>             Project: Hadoop Common
>          Issue Type: Improvement
>            Reporter: Colin Patrick McCabe
>            Assignee: Colin Patrick McCabe
>            Priority: Minor
> Development appears to have stopped on hadoop-pipes upstream for the last few years,
aside from very basic maintenance.  Hadoop streaming seems to be a better alternative, since
it supports more programming languages and is better implemented.
> There were no responses to a message on the mailing list asking for users of Hadoop pipes...
and in my experience, I have never seen anyone use this.  We should remove it to reduce our
maintenance burden and build times.
