@mdymczyk looks nice! I'd like to verify this change. should I run sparkling water to do that?

edit: the answer is yes. below are the steps to reproduce the feature and test this PR

[micahstubbs]

./gradlew clean publishToMavenLocal

[micahstubbs]

to resolve internal/fs error:
from h2o-3 root directory rm -rf h2o-web/node_modules

[micahstubbs]

[micahstubbs]

now we build sparkling water
./gradlew build -x test -x integTest

[micahstubbs]

set version as well, since another h2o-3 major release has happened

[micahstubbs]

now we start Sparkling Water
cd bin
./sparkling-shell

scala> import org.apache.spark.h2o._
scala> H2OContext.getOrCreate(sc)

[micahstubbs]

[micahstubbs]

Uncaught ReferenceError: Unable to process binding "with: function (){return output }"(…)

[micahstubbs]

here is the block of code from flow-lib.js that produces the error

@micahstubbs turns out I just had to rebase master onto this branch and all is working, you can retest again.

1. in h2o-3 run ./gradlew clean
2. in h2o-flow do git pull and make
3. in h2o-3 copy all .js files from h2o-web/src/main/resources/www/flow/js to h2o-web/lib/h2o-flow/build/js cp h2o-web/src/main/resources/www/flow/js/* h2o-web/lib/h2o-flow/build/js/
4. in h2o-3 run ./gradlew publishToMavenLocal -x test
5. in sparkling water run ./gradlew clean build -x test -x integTest
6. in SW run bin/sparkling-shell
7. in the shell run:

import org.apache.spark.h2o._
H2OContext.getOrCreate(sc)

In FlowUI run the SVM flow.

3. in h2o-3 copy all .js files from
   h2o-web/src/main/resources/www/flow/js
   to
   h2o-web/lib/h2o-flow/build/js
   the command for that is
   cp h2o-web/src/main/resources/www/flow/js/* h2o-web/lib/h2o-flow/build/js/

@lo5 is this the sort of step that we should add to the Flow Makefile?

[micahstubbs]

just verified that the ROC plot does render 🎉

here are the images from this last step:

In FlowUI run the SVM flow.

first we view example flows

then we click Spark_SVM_Model.flow

we see some code cells. let's run them!

the result of running the code cells is an svm-model

when we click on the svm-model, we see the ROC plot

[micahstubbs]

now we just need an answer from @lo5 on this question about how best to automate this manual copy step in build process

[lo5]

@micahstubbs The usual release process is:

1. ./release.sh 1.2.3 to push a new release to NPM.
2. Bump the version in bower.json: https://github.com/h2oai/h2o-3/blob/master/h2o-web/bower.json

[micahstubbs]

will now release 0.4.52 with a commit to master

[micahstubbs]

ok, so it looks like the script ./release.sh 0.4.52 creates the commit for you. nice.
