Eyal Allweil commented on DATAFU-95:
As an immediate, easy-to-do improvement, writing what Java version is required
in the main README on GitHub would be great.

[jira] [Created] (DATAFU-114) Make FirstTupleFromBag implement Accumulator
Eyal Allweil created DATAFU-114: --- Summary: 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 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
[jira] [Updated] (DATAFU-114) Make FirstTupleFromBag implement Accumulator
[ https://issues.apache.org/jira/browse/DATAFU-114?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Eyal Allweil updated DATAFU-114: Attachment: FirstTupleFromBag.java I wasn't able to test this patch because I can't get the build working on my system (Ubuntu LTS) .. I'm getting the error described [here|https://issues.apache.org/jira/browse/DATAFU-95]. I can't seem to make Gradle use a different Java to get it to compile. However, since the implementation of Accumulator is relatively straightforward, I hopefully haven't made any mistakes and I would appreciate if someone whose build is working tried it out and pulled the patch. > 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 > 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.
