Weekly Minutes

[Trevor Grant]

## Weekly community meeting
[Subscribe](mailto:user-subscr...@mahout.apache.org) to the Mahout User
list to ask for details on joining.

### Attendees
* Tommy Naugle
* Trevor Grant


All old and new business was pushed to next meeting due to lack of quorum.

Tommy and Trevor jointly reviewed [PR #442](
https://github.com/apache/mahout/pull/442).
The tl;dr is that it will be merged following some clean up on the git log.
(Trevor walked Tommy through a chatGPT he made about how to clean it up).

Don't forget the Community Happy Hour on Monday 4/29! (Ask for link on
user@m.a.o or the #mahout channel on the-asf.slack.com, all are welcome!)

(That all got posted to the website, since y'all are on these mailing lists
already, the story behind the story is we don't have a link yet, however if
you're interested in joining the community calls- the weekly Qumat one is:

Mahout-Q

Re: How to build an app.

[Trevor Grant]

Hi Amanda,

Thanks for sticking around this time!
first, the link you're looking for is here
https://github.com/apache/mahout/blob/trunk/website/documentation/users/environment/how-to-build-an-app.md

Most of the active dev at the moment is moving Mahout towards a python
based quantum interface. It's still in alpha at the moment, but there is
some good background reading on the slack channel, or (I see you have an
.edu address) you can use your institution to read anything you can on
Quantum Neural Networks (qNN) or any quantum machine learning. (Alas, the
wall of noise).

But most importantly, if you're building an app, don't be shy about asking
for help- the slack channel is usually a faster way to get help (bc it
buzz's at us when there's a message, and we haven't figured out how to
disable the notification like we did for email :D

Nice to meet you, looking forward to further conversation,

tg

Re: Interested in Contributing to Apache Mahout

[Trevor Grant]

Hi Jasmine,

We'd love to have you help out! there's a list of issues for people just
getting started to work on... somewhere, I think finding it and making it
somewhere other people can find is a todo on my list. There's a community
call next Wednesday too,  that might be a good place to introduce yourself
and meet some of us.

Project Idea - Quantum (tangent to Project Idea - Blockchain)

[Trevor Grant]

Since we're discussing new possible directions for the project anyway-

I would be able to dedicate more cycles to creating an abstracting over
various quantum computing implementations (see a list here[1]).

I don't think it's an either/or wrt blockchain stuff, and there's probably
even some overlap. But I would plan on doing it in Python (not Java or
Scala).

Mahout Blog

[Trevor Grant]

Hey all,

I was just on the site and remembered about the Mahout blog and wanted to
note 2 things.

1) The outcome of the thread on block chain stuff and the upcoming meeting
should get recapped in some sort of post- I can do it, just someone please
remind me.

2) If anyone wants to get involved with the project but isn't sure what a
good first commit would be- we'd always love blog posts.

The posts are typical Jeckyll style- here is an example[1] reach out if you
need/want more help.

I don't think we set a time / place to meet tonight-

Log4j, CVE-2021-44228, and Mahout

[Trevor Grant]

Many of you have probably become aware of Log4j's vulnerability to
CVE-2021-44228 recently.

Though Mahout is a sleepy project, we are vigilant and want you to know we
are aware of the issue and have been monitoring.

First, let me assure you that since Mahout (like over 90% of log4j users)
is on version 1.x it is not vulnerable to the JDNI remote execution attack
[1]. That said, 1.x was set for EOL in 2015, so it's probably time to
update that. I've made a JIRA ticket (MAHOUT-2140)[2].

The update isn't too complex, but it's also not trivial, and most
importantly it's not critical so you're not endangering anything running
Mahout, and we'll hopefully get it in for the next release in a couple of
months.

Hope this helps everyone feel secure going into their holiday season.

[jira] [Created] (MAHOUT-2140) Upgrade Log4j per CVE-2021-44228

[Trevor Grant (Jira)]

 Summary: Upgrade Log4j per CVE-2021-44228
 Key: MAHOUT-2140
 URL: https://issues.apache.org/jira/browse/MAHOUT-2140
 Project: Mahout
  Issue Type: Bug
Reporter: Trevor Grant


h2. CVE-2021-44228 was a pretty big vulnerability. Since we're still on log4j 
1.x the upgrade is non-trivial, but also maybe not at serious for us.

Hey all,

I'm still putzing w pymahout as i have time-

I can do incore stuff but keep getting "Not Found" errors when attempting
to access scala stuff in py4j, almost sure its just me being a dumb dumb.

If anyone has some py4j skills or is otherwise interested in helping out-
pls respond i was thinking maybe we could get a working group going.

I can point to my code/docker container i use for testing too.

Yea- I was buried in work, but the clouds are beginning to part.

PyMahout (incore) (alpha v0.1)

[Trevor Grant]

Hey all,

I made a branch for a thing I'm toying with. PyMahout.

See https://github.com/rawkintrevo/pymahout/tree/trunk

Right now, its sort of dumb- it just makes a couple of random incore
matrices... but it _does_ make them.

Next I want to show I can do something with DRMs.

Once I know its all possible- Ill make a batch of JIRA tickets and we can
start implementing a python like package so that in theory in a pyspark
workbook you could

```jupyter
!pip install pymahout


import pymhout

# do pymahot things here... in python.

```

So if you're interested in helping /playing- reach out on here or direct-
if there is a bunch of interest I can commit all of this to a branch as we
play with it.

Thanks!

Cancelling Weekly Meetings Until 2021

Re: [DISCUSS] Move time of weekly meeting

[Trevor Grant]

OK, let's move them to Tuesdays, mid afternoon PST. And see how those work
out.

This weeks is a holiday in the US so I was going to cancel the weekly
meeting anyway.

I'm going to be moving beginning of next week, so unless someone else can
cover it- let's do the next weekly meeting on Tuesday December 8th.

Thanks all!

Re: Community Call

[Trevor Grant]

We had a good meeting- the minutes can be found here[1]. Note- we'll be
posting minutes for the meeting going forward andyou can see them on the
front page of the website.

The synopsis:

We found a few issues in the docs and created JIRA tickets.  Multiple
people on the call volunteered to work on various doc issues. Trevor
apologized he hasn't gotten started on the Python bindings due to the
unseasonably nice weather in Chicago, but assures everyone it will be awful
here soon enough and will get cracking then.

Hope all who couldn't make it will be there next week!

Mahout Community Call

[Trevor Grant]

Hey all!

We'll be restarting our Mahout Community Calls this week.

The first one will be Friday Oct 30 12:00 pm -1:00 pm (Central Standard
Time), that's 17:00-18:00 UTC.

The purpose of this call will be to give developers a chance to see what
others are working on and to understand where and how we might help each
other.

Looking forward to seeing you all there!

Re: [ANNOUNCE] Apache Mahout 14.1 Release

[Trevor Grant]

Actually. I'm a dummy. Yes we can all build it. The only part that broke
was the automated part.

For reference- here is the JIRA ticket w infra [1]
You can see the workflow [2]

The jist is- you pull, run /website/build-site.sh, then push the output to
`asf-site` branch. (There's a touch more nuance to it than that, but that's
the high level).

If INFRA doesn't even respond by end of day (e.g. assign someone) I guess
I'll add and build it myself (unless someone else does first). Just
remember to open PR of code you changed on the website. In general among
committers, no reviews are needed for website updates so whoever is
watching feel free to just do it.

Re: [ANNOUNCE] Apache Mahout 14.1 Release

[Trevor Grant]

I think we're blocked by same thing that is blocking us announcing on
announce@ we can't update the website, so we can't add download links. :(

Infra ticket is filed, will be a quick fix once we get tokens from them.

Re: [DISCUSS] Release 14.1, RC7

[Trevor Grant]

I'm back- will test tonight I hope.

Pat can give a binding, and knows the most about the SBT- so I'd like to
see a +1 from him (or -1 if it doesn't work).

I have a binding.

Implicitly, AKM would have a binding +1, but the release master normally
doesn't vote until the end.

So that would be 3, but it would be worth exploring a new PMC addition.

Re: [VOTE] Release 14.1, RC6

[Trevor Grant]

Thank you so much for getting this out Andrew.

I verified all checksums/sigs.

I successfully built the source including all tests. (I did this in the
public docker container rawkintrevo/mahout-builder-base)

I also tested the binaries in the public docker container
rawkintrevo/mahoutgui , but bashing into the running container, unpacking
both the binary archives, and then aiming and running the mahout example
notebook in turn against each of the unpacked binaries from each of the
archives.  I did this in place of spark-shell, as I think it's a more
elegant solution going forward, but would encourage others to test against
mahout spark-shell.

So given all of that, I give an enthusiastic +1

Re: Who has not migrated yet?

[Trevor Grant]

The Jenkins nightlies don't work, will fix after build is fixed.

In essence, the whole thing needs refactored anyway once the build is done
being refactored, which I think it is, but I've been dealing w a plumbing
emergency the last two days, so maybe I can migrate this weekend?

Short if the long of it- i saw that the old scripts will be saved, so just
shut it down and we can read the old configs when rebuilding on git actions.

[jira] [Created] (MAHOUT-2119) Migrate from Jenkins to Git Actions

Per mailing list from [~cdutz]  [1] we need to migrate away from current 
Jenkins CI build.

Talked to infra- moving to git actions.

Re: Someone should get started on migrating your build jobs to ci-builds.apache.org

I talked to Gavin in the @asfinfra channel- we just need to get whatever
username/password jenkins uses and provide those as secrets for git actions
and we are good to go.

Re: Someone should get started on migrating your build jobs to ci-builds.apache.org

[Trevor Grant]

Cool, thanks Holden.

@Christofer Dutz  Github actions are in essence
a CI that is github native.  Sounds like there is clearance for ASF
projects to use them one way or the other, so I'll take point on exploring
what we need to do to shut down Jenkins and migrate to that.

Does anyone know what is going on with `mahout-nightly` in jenkins? like why 
does it keep breaking then magically healing itsself?

Re: Mahout Con (An ApacheCon@Home Track)

[Trevor Grant]

Hey all,

I've been out of pocket for the last week- but I saw today the CFP ends
Monday.  If anyone who is interested could submit a talk with their name /
title.

There's no limit on space, so we're keen to accept all talks of value, but
having your name and a rough abstract in the system is the important thing.

I'm pretty sure we can edit the abstracts talks later, but jic check
spelling :)

Mahout Con (An ApacheCon@Home Track)

[Trevor Grant]

Hey Mahout users and devs!

This year at ApacheCon(@Home), we're doing a Mahout track!

We want to see lots of things about Mahout, and we'll (hopefully get
recordings and put them on the website).

Haven't you always wanted to give a talk on Mahout ? well here's your
chance.

We're taking anything Mahout related, but in case you need some ideas to
get you started:

* Getting Started with Mahout: From Installing to Basic Samsera Shell (to
Apache Zeppelin integration?!)

* Deep Dive on Specific Features of Mahout : (e.g. Pat may do a CCO)

* How our company used Apache Mahout to implement features (I'm looking at
you Cars.com :P )

* Mahout on Kubeflow (I'm going to do this one, but don't let that stop you
from doing one yourself!)

* Mahout + Docker/K8s (A bit of overlap, with prior, but no shame there).

* And much much more.

The CFP is available here https://www.apachecon.com/cfp.html please fill it
out,
https://www.apachecon.com/acna2020/cfp.html

And thanks all!

Sorry for the noise...

[Trevor Grant]

Hey all, you probably just saw that I "closed" like 50 issues.

What actually happened is I deleted the `master` branch and those issues
were all automatically closed. If you had a PR out and still want it
considered, please reopen it against the new `trunk` default branch.

As such I think this will be a nice bit of hygiene for our PRs.

Sorry for blowing up your inboxes.

Re: [VOTE] Renaming primary branch

[Trevor Grant]

For reasons, I'm ending this vote early.  Motion carries- anyone who wants
more info can dm me (e.g. respond off list).

[VOTE] Renaming primary branch

[Trevor Grant]

Per some discussion on diversity@a.o , we want to open the vote for
renaming our primary branch from `master` to `prod_ready`.

This is a trivial change, that if it makes our community more welcoming to
just one potential contributor of color is worth it in our opinion.

The vote will remain open for 96 hours (the typical 72 hours + 24 hours for
anyone who is observing #shutdownstem tomorrow, June 10th).

+1 binding.

[DISCUSS] Move from JIRA to git issues

[Trevor Grant]

Saw a comment on the Streams slack channel- apparently its possible for us
(Apache Projects) to migrate to git issues.

Advantages:
- People already there / easier work flow
- encourages people w/o jira access to get involved w project

Disadvantages
- Need to go through all the old outstanding issues and do some clean up to
move them over.

Any one have any feels about this?

Apparently the process is: we vote on it- infra does it.

Note, this is a discuss thread, not a vote thread.

[ANNOUNCE] New Committer: Christofer Dutz

[Trevor Grant]

The Project Management Committee (PMC) for Apache Mahout
has invited Christofer Dutz to become a committer and we are pleased
to announce that they have accepted.

Chris has been a huge help in assisting us with cleaning up the Mahout
build.

Being a committer enables easier contribution to the
project since there is no need to go via the patch
submission process. This should enable better productivity.

Re: Hi ... need some help?

[Trevor Grant]

Hey- sorry for not following up here. I thought I had emailed this last
week ( I was actually just digging around to find out why no one had
responded ... the answer was I never sent the email.)

Built a docker container with Ubuntu 18.04 ( has java 11)

Kept failing on
```
java.lang.IllegalArgumentException: Unsupported class file major version 55
  at org.apache.xbean.asm6.ClassReader.(ClassReader.java:166)
```

This is a known issue in Spark too, feel free to google it - but the gist
is- we won't be able to officially support Java 11, though a clever person
_can_ hack around this.  Spark also does not support Java 11 for same
reasons.

Built another container with the following docker file:
```
FROM openjdk:8
RUN apt update && apt install git maven -y
RUN git clone https://github.com/chrisdutz/mahout.git /mahout
RUN cd /mahout && mvn clean package
```

This one fails in the old "Map Reduce" based Mahout.  In the tests there's
1000 "NoClassDef" and Null pointed failures, which leads me to believe
something got moved in the refactor. (I've got a text file of the output I
can send too, but this, bc of Dockers, _should_ be very reproducible).

If someone else could confirm, that would be cool.

Again, not having a failure- it just always hangs in that one place- either
on that test or on the next one I'm not sure.

Re: Hi ... need some help?

[Trevor Grant]

I misspoke- it was in the Scala bindings, this is the last line to print
off:

https://github.com/apache/mahout/blob/758cfada62556d679c445416dff9d9fb2a3c4e59/core/src/test/scala/org/apache/mahout/math/scalabindings/MatrixOpsSuite.scala#L222

Hope akm or someone else can test to help me figure out if its my machine
or a real issue.

Re: Hi ... need some help?

[Trevor Grant]

On Java 8 when I build with tests it always hangs on
```
Average assignment seqSparse2seqSparse time: 25.776 ms
Average assignment seqSparse2seqSparse via Random Access Sparse time:
224.714 ms
```

It seems like that's in the Mahout Core section. What is our new "official
target" java? I have 8,11,13 on this machine, but can install 9,10 if one
of them is the new official that we are using.

Is JDK 13 supposed to work now? I was able to get archives if I skipped
tests, but w Java 8 the tests hung, and Java 13 tests had errors.

Re: Migration of Hadoop labelled nodes to new dedicated Master

[Trevor Grant]

Since we're not really doing anything with Hadoop anymore should we just
ask to be dropped front his thread?

Or does someone want to step up and make sure the old MR stuff maintains
compatibility with this?
