Matthew Hayes commented on DATAFU-114:
--------------------------------------
Try the patch in DATAFU-95 I just attached and see if that helps your build
issue. It should work with JDK 1.7 now.
By the way, I've had good success switching Java versions using jenv
(https://github.com/gcuisinier/jenv). Haven't tried it on Ubuntu but it seems
like it would work.
Also in the future a patch+RB makes it easier to review and apply the changes.
> Make FirstTupleFromBag implement Accumulator
> --------------------------------------------
>
> Key: DATAFU-114
> URL: https://issues.apache.org/jira/browse/DATAFU-114
> Project: DataFu
> Issue Type: Improvement
> Affects Versions: 1.3.0
> Environment: All
> Reporter: Eyal Allweil
> Priority: Minor
> Labels: easyfix, newbie, performance
> Fix For: 1.3.1
>
> Attachments: FirstTupleFromBag.java
>
>
> FirstTupleFromBag only needs the first tuple from the bag, but because it
> doesn't implement Accumulator the entire bag needs to be passed to it
> in-memory. The fix is very minor and will make the UDF support large bags.
